Using conda in Windows Batch script exits early#

In conda 4.6+, the way that you interact with conda goes through a batch script (%PREFIX%\condabin\conda.bat). Unfortunately, this means it's a little complicated to use conda from other batch scripts. When using batch scripts from within batch scripts, you must prefix your command with CALL. If you do not do this, your batch script that calls conda will exit immediately after the conda usage. In other words, if you write this in a .bat file:

conda create myenv python
conda activate myenv
echo test

Neither the activation, nor the echo will happen. You must write this in your batch script:

CALL conda create myenv python
CALL conda activate myenv
echo test

This is known behavior with cmd.exe, and we have not found any way to change it.

NumPy MKL library load failed#

Error messages like

Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll


The ordinal 241 could not be located in the the dynamic link library


NumPy is unable to load the correct MKL or Intel OpenMP runtime libraries. This is almost always caused by one of two things:

  1. The environment with NumPy has not been activated.

  2. Another software vendor has installed MKL or Intel OpenMP (libiomp5md.dll) files into the C:\Windows\System32 folder. These files are being loaded before Anaconda's and they're not compatible.


If you are not activating your environments, start with doing that. There's more info at Activating environments. If you are still stuck, you may need to consider more drastic measures.

  1. Remove any MKL-related files from C:\Windows\System32. We recommend renaming them to add .bak to the filename to effectively hide them. Observe if any other software breaks. Try moving the DLL files alongside the .exe of the software that broke. If it works again, you can keep things in the moved state - Anaconda doesn't need MKL in System32, and no other software should need it either. If you identify software that is installing software here, please contact the creators of that software. Inform them that their practice of installing MKL to a global location is fragile and is breaking other people's software and wasting a lot of time. See the list of guilty parties below.

  2. You may try a special DLL loading mode that Anaconda builds into Python. This changes the DLL search path from System32 first to System32 as another entry on PATH, allowing libraries in your conda environment to be found before the libraries in System32. Control of this feature is done with environment variables. Only Python builds beyond these builds will react to these environment variables:

    • Python 2.7.15 build 14

    • Python 3.6.8 build 7

    • Python 3.7.2 build 8

    To update Python from the defaults channel:

    conda update -c defaults python


    Anaconda has built special patches into its builds of Python to enable this functionality. If you get your Python package from somewhere else (e.g. conda-forge), these flags may not do anything.

    Control environment variables:





    To set variables on Windows, you may use either the CLI or a Windows GUI.

    These should be set to a value of 1 to enable them. For example, in a terminal:

SSL connection errors#

This is a broad umbrella of errors with many causes. Here are some we've seen.


If you're on Windows and you see this error, look a little further down in the error text. Do you see something like this?:

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'\', port=443): Max retries exceeded with url: /pkgs/r/win-32/repodata.json.bz2 (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available."))'))

The key part there is the last bit:

Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available.")

Conda is having problems because it can't find the OpenSSL libraries that it needs.


You may observe this error cropping up after a conda update. More recent versions of conda and more recent builds of Python are more strict about requiring activation of environments. We're working on better error messages for them, but here's the story for now. Windows relies on the PATH environment variable as the way to locate libraries that are not in the immediate folder, and also not in the C:\Windows\System32 folder. Searching for libraries in the PATH folders goes from left to right. If you choose to put Anaconda's folders on PATH, there are several of them:

  • (install root)

  • (install root)/Library/(MSYS2 env)/bin ## dependent on MSYS2 packages

  • (install root)/Library/mingw-w64/bin

  • (install root)/Library/usr/bin

  • (install root)/Library/bin

  • (install root)/Scripts

  • (install root)/bin

  • (install root)/condabin

Early installers for Anaconda put these on PATH. That was ultimately fragile because Anaconda isn't the only software on the system. If other software had similarly named executables or libraries, and came earlier on PATH, Anaconda could break. On the flip side, Anaconda could break other software if Anaconda were earlier in the PATH order and shadowed any other executables or libraries. To make this easier, we began recommending "activation" instead of modifying PATH. Activation is a tool where conda sets your PATH, and also runs any custom package scripts which are often used to set additional environment variables that are necessary for software to run (e.g. JAVA_HOME). Because activation runs only in a local terminal session (as opposed to the permanent PATH entry), it is safe to put Anaconda's PATH entries first. That means that Anaconda's libraries get higher priority when you're running Anaconda but Anaconda doesn't interfere with other software when you're not running Anaconda.

Anaconda's Python interpreter included a patch for a long time that added the (install root)/Library/bin folder to that Python's PATH. Unfortunately, this interfered with reasoning about PATH at all when using that Python interpreter. We removed that patch in Python 3.7.0, and we regret that this has caused problems for people who are not activating their environments and who otherwise do not have the proper entries on PATH. We're experimenting with approaches that will allow our executables to be less dependent on PATH and more self-aware of their needed library load paths. For now, though, the only solutions to this problem are to manage PATH properly.

Our humble opinion is that activation is the easiest way to ensure that things work. See more information on activation in Activating environments.


Use shells opened from Anaconda Navigator. If you use a GUI IDE and you see this error, ask the developers of your IDE to add activation for conda environments.

SSL certificate errors#


Installing packages may produce a "connection failed" error if you do not have the certificates for a secure connection to the package repository.


Pip can use the --use-feature=truststore option to use the operating system certificate store. This may be of help in typically corporate environments with https traffic inspection, where the corporate CA is installed in the operating system certificate store:

pip install --use-feature=truststore

Conda has a similar option:

conda config --set ssl_verify truststore

Alternatively, pip can use the --trusted-host option to indicate that the URL of the repository is trusted:

pip install --trusted-host

Conda has three similar options.

  1. The option --insecure or -k ignores certificate validation errors for all hosts.

    Running conda create --help shows:

    Networking Options:
      -k, --insecure        Allow conda to perform "insecure" SSL connections and
                            transfers. Equivalent to setting 'ssl_verify' to
  2. The configuration option ssl_verify can be set to False.

    Running conda config --describe ssl_verify shows:

    # # ssl_verify (bool, str)
    # #   aliases: verify_ssl
    # #   conda verifies SSL certificates for HTTPS requests, just like a web
    # #   browser. By default, SSL verification is enabled and conda operations
    # #   will fail if a required URL's certificate cannot be verified. Setting
    # #   ssl_verify to False disables certification verification. The value for
    # #   ssl_verify can also be (1) a path to a CA bundle file, (2) a path to a
    # #   directory containing certificates of trusted CA, or (3) 'truststore'
    # #   to use the operating system certificate store.
    # #
    # ssl_verify: true

    Running conda config --set ssl_verify false modifies ~/.condarc and sets the -k flag for all future conda operations performed by that user. Running conda config --help shows other configuration scope options.

    When using conda config, the user's conda configuration file at ~/.condarc is used by default. The flag --system will instead write to the system configuration file for all users at <CONDA_BASE_ENV>/.condarc. The flag --env will instead write to the active conda environment's configuration file at <PATH_TO_ACTIVE_CONDA_ENV>/.condarc. If --env is used and no environment is active, the user configuration file is used.

  3. The configuration option ssl_verify can be used to install new certificates.

    Running conda config --describe ssl_verify shows:

    # # ssl_verify (bool, str)
    # #   aliases: verify_ssl
    # #   conda verifies SSL certificates for HTTPS requests, just like a web
    # #   browser. By default, SSL verification is enabled, and conda operations
    # #   will fail if a required URL's certificate cannot be verified. Setting
    # #   ssl_verify to False disables certification verification. The value for
    # #   ssl_verify can also be (1) a path to a CA bundle file, (2) a path to a
    # #   directory containing certificates of trusted CA, or (3) 'truststore'
    # #   to use the operating system certificate store.
    # #
    # ssl_verify: true

    Your network administrator can give you a certificate bundle for your network's firewall. Then ssl_verify can be set to the path of that certificate authority (CA) bundle and package installation operations will complete without connection errors.

    When using conda config, the user's conda configuration file at ~/.condarc is used by default. The flag --system will instead write to the system configuration file for all users at <CONDA_BASE_ENV>/.condarc. The flag --env will instead write to the active conda environment's configuration file at <PATH_TO_ACTIVE_CONDA_ENV>/.condarc. If --env is used and no environment is active, the user configuration file is used.

SSL verification errors#


This error may be caused by lack of activation on Windows or expired certifications:

SSL verification error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)


Make sure your conda is up-to-date: conda --version

If not, run: conda update conda

Try using the operating system certificate store. Set you ssl_verify variable to truststore using the following command:

conda config --set ssl_verify truststore

If using the operating system certificate store does not solve your issue, temporarily set your ssl_verify variable to false, upgrade the requests package, and then set ssl_verify back to true using the following commands:

conda config --set ssl_verify false
conda update requests
conda config --set ssl_verify true

You can also set ssl_verify to a string path to a certificate, which can be used to verify SSL connections. Modify your .condarc and include the following:

ssl_verify: path-to-cert/chain/filename.ext

If the repository uses a self-signed certificate, use the actual path to the certificate. If the repository is signed by a private certificate authority (CA), the file needs to include the root certificate and any intermediate certificates.

Permission denied errors during installation#


The umask command determines the mask settings that control how file permissions are set for newly created files. If you have a very restrictive umask, such as 077, you get "permission denied" errors.


Set a less restrictive umask before calling conda commands. Conda was intended as a user space tool, but often users need to use it in a global environment. One place this can go awry is with restrictive file permissions. Conda creates links when you install files that have to be read by others on the system.

To give yourself full permissions for files and directories but prevent the group and other users from having access:

  1. Before installing, set the umask to 007.

  2. Install conda.

  3. Return the umask to the original setting:

    umask 007
    conda install
    umask 077

For more information on umask, see

Permission denied errors after using sudo conda command#


Once you run conda with sudo, you must use sudo forever. We recommend that you NEVER run conda with sudo.

Already installed error message#


If you are trying to fix conda problems without removing the current installation and you try to reinstall Miniconda or Anaconda to fix it, you get an error message that Miniconda or Anaconda is already installed and you cannot continue.


Install using the --force option.

Download and install the appropriate Miniconda for your operating system from the Miniconda download page using the force option --force or -f:

bash -f


Substitute the appropriate filename and version for your operating system.


Be sure that you install to the same location as your existing install so it overwrites the core conda files and does not install a duplicate in a new folder.

Conda reports that a package is installed, but it appears not to be#

Sometimes conda claims that a package is already installed but it does not appear to be, for example, a Python package that gives ImportError.

There are several possible causes for this problem, each with its own solution.


You are not in the same conda environment as your package.


  1. Make sure that you are in the same conda environment as your package. The conda info command tells you what environment is currently active under default environment.

  2. Verify that you are using the Python from the correct environment by running:

    import sys


For Python packages, you have set the PYTHONPATH or PYTHONHOME variable. These environment variables cause Python to load files from locations other than the standard ones. Conda works best when these environment variables are not set, as their typical use cases are obviated by conda environments and a common issue is that they cause Python to pick up the wrong or broken versions of a library.


For Python packages, make sure you have not set the PYTHONPATH or PYTHONHOME variables. The command conda info -a displays the values of these environment variables.

  • To unset these environment variables temporarily for the current terminal session, run unset PYTHONPATH.

  • To unset them permanently, check for lines in the files:

    • If you use bash---~/.bashrc, ~/.bash_profile, ~/.profile.

    • If you use zsh---~/.zshrc.

    • If you use PowerShell on Windows, the file output by $PROFILE.


You have site-specific directories or, for Python, you have so-called site-specific files. These are typically located in ~/.local on macOS and Linux. For a full description of the locations of site-specific packages, see PEP 370. As with PYTHONPATH, Python may try importing packages from this directory, which can cause issues.


For Python packages, remove site-specific directories and site-specific files.


For C libraries, the following environment variables have been set:


  • Linux---LD_LIBRARY_PATH.

These act similarly to PYTHONPATH for Python. If they are set, they can cause libraries to be loaded from locations other than the conda environment. Conda environments obviate most use cases for these variables. The command conda info -a shows what these are set to.




Occasionally, an installed package becomes corrupted. Conda works by unpacking the packages in the pkgs directory and then hard-linking them to the environment. Sometimes these get corrupted, breaking all environments that use them. They also break any additional environments since the same files are hard-linked each time.


Run the command conda install -f to unarchive the package again and relink it. It also does an MD5 verification on the package. Usually if this is different it is because your channels have changed and there is a different package with the same name, version, and build number.


This breaks the links to any other environments that already had this package installed, so you have to reinstall it there, too. It also means that running conda install -f a lot can use up significant disk space if you have many environments.


The -f flag to conda install (--force) implies --no-deps, so conda install -f package does not reinstall any of the dependencies of package.

pkg_resources.DistributionNotFound: conda==3.6.1-6-gb31b0d4-dirty#


The local version of conda needs updating.


Force reinstall conda. A useful way to work off the development version of conda is to run python develop on a checkout of the conda GitHub repository. However, if you are not regularly running git pull, it is a good idea to un-develop, as you will otherwise not get any regular updates to conda. The normal way to do this is to run python develop -u.

However, this command does not replace the conda script itself. With other packages, this is not an issue, as you can just reinstall them with conda, but conda cannot be used if conda is installed.

The fix is to use the ./bin/conda executable in the conda git repository to force reinstall conda. That is, run ./bin/conda install -f conda. You can then verify with conda info that you have the latest version of conda, and not a git checkout. The version should not include any hashes.

macOS error "ValueError unknown locale: UTF-8"#


This is a bug in the macOS Terminal app that shows up only in certain locales. Locales are country-language combinations.


  1. Open Terminal in /Applications/Utilities

  2. Clear the Set locale environment variables on startup checkbox.


This sets your LANG environment variable to be empty. This may cause Terminal to use incorrect settings for your locale. The locale command in Terminal tells you what settings are used.

To use the correct language, add a line to your bash profile, which is typically ~/.profile:

export LANG=your-lang


Replace your-lang with the correct locale specifier for your language.

The command locale -a displays all the specifiers. For example, the language code for US English is en_US.UTF-8. The locale affects what translations are used when they are available and also how dates, currencies, and decimals are formatted.

AttributeError or missing getproxies#

When running a command such as conda update ipython, you may get an AttributeError: 'module' object has no attribute 'getproxies'.


This can be caused by an old version of requests or by having the PYTHONPATH environment variable set.


Update requests and be sure PYTHONPATH is not set:

  1. Run conda info -a to show the requests version and various environment variables such as PYTHONPATH.

  2. Update the requests version with pip install -U requests.

  3. Clear PYTHONPATH:

    • On Windows, clear it the environment variable settings.

    • On macOS and Linux, clear it by removing it from the bash profile and restarting the shell.

Shell commands open from the wrong location#

When you run a command within a conda environment, conda does not access the correct package executable.


In both bash and zsh, when you enter a command, the shell searches the paths in PATH one by one until it finds the command. The shell then caches the location, which is called hashing in shell terminology. When you run command again, the shell does not have to search the PATH again.

The problem is that before you installed the program, you ran a command which loaded and hashed another version of that program in some other location on the PATH, such as /usr/bin. Then you installed the program using conda install, but the shell still had the old instance hashed.


Reactivate the environment or run hash -r (in bash) or rehash (in zsh).

When you run conda activate, conda automatically runs hash -r in bash and rehash in zsh to clear the hashed commands, so conda finds things in the new path on the PATH. But there is no way to do this when conda install is run because the command must be run inside the shell itself, meaning either you have to run the command yourself or used a source file that contains the command.

This is a relatively rare problem, since this happens only in the following circumstances:

  1. You activate an environment or use the root environment, and then run a command from somewhere else.

  2. Then you conda install a program, and then try to run the program again without running activate or deactivate.

The command type command_name always tells you exactly what is being run. This is better than which command_name, which ignores hashed commands and searches the PATH directly. The hash is reset by conda activate or by hash -r in bash or rehash in zsh.

Programs fail due to invoking conda Python instead of system Python#


After installing Anaconda or Miniconda, programs that run python switch from invoking the system Python to invoking the Python in the root conda environment. If these programs rely on the system Python to have certain configurations or dependencies that are not in the root conda environment Python, the programs may crash. For example, some users of the Cinnamon desktop environment on Linux Mint have reported these crashes.


Edit your .bash_profile and .bashrc files so that the conda binary directory, such as ~/miniconda3/bin, is no longer added to the PATH environment variable. You can still run conda activate and conda deactivate by using their full path names, such as ~/miniconda3/bin/conda.

You may also create a folder with symbolic links to conda activate and conda deactivate and then edit your .bash_profile or .bashrc file to add this folder to your PATH. If you do this, running python will invoke the system Python, but running conda commands, conda activate MyEnv, conda activate root, or conda deactivate will work normally.

After running conda activate to activate any environment, including after running conda activate root, running python will invoke the Python in the active conda environment.

UnsatisfiableSpecifications error#


Some conda package installation specifications are impossible to satisfy. For example, conda create -n tmp python=3 wxpython=3 produces an "Unsatisfiable Specifications" error because wxPython 3 depends on Python 2.7, so the specification to install Python 3 conflicts with the specification to install wxPython 3.

When an unsatisfiable request is made to conda, conda shows a message such as this one:

The following specifications were found to be in conflict:
- python 3*
- wxpython 3* -> python 2.7*
Use ``conda search <package> --info`` to see the dependencies
for each package.

This indicates that the specification to install wxpython 3 depends on installing Python 2.7, which conflicts with the specification to install Python 3.


Use conda search wxpython --info or conda search 'wxpython=3' --info to show information about this package and its dependencies:

wxpython 3.0 py27_0
file name   : wxpython-3.0-py27_0.tar.bz2
name        : wxpython
version     : 3.0
build number: 0
build string: py27_0
channel     : defaults
size        : 34.1 MB
date        : 2014-01-10
fn          : wxpython-3.0-py27_0.tar.bz2

priority    : 2
schannel    : defaults
url         :
    python 2.7*

By examining the dependencies of each package, you should be able to determine why the installation request produced a conflict and modify the request so it can be satisfied without conflicts. In this example, you could install wxPython with Python 2.7:

conda create -n tmp python=2.7 wxpython=3

Package installation fails from a specific channel#


Sometimes it is necessary to install a specific version from a specific channel because that version is not available from the default channel.


The following example describes the problem in detail and its solution.

Suppose you have a specific need to install the Python cx_freeze module with Python 3.4. A first step is to create a Python 3.4 environment:

conda create -n py34 python=3.4

Using this environment you should first attempt:

conda install -n py34 cx_freeze

However, when you do this you get the following error:

Using Anaconda Cloud api site

Solving package specifications: .
Error: Package missing in current osx-64 channels:

You can search for packages on with

  anaconda search -t conda cx_freeze

The message indicates that cx_freeze cannot be found in the default package channels. However, there may be a community-created version available and you can search for it by running the following command:

$ anaconda search -t conda cx_freeze

In this example, there are 4 different places that you could try to get the package. None of them are officially supported or endorsed by Anaconda, but members of the conda community have provided many valuable packages. If you want to go with public opinion, then the web interface provides more information:

Notice that the pyzo organization has by far the most downloads, so you might choose to use their package. If so, you can add their organization's channel by specifying it on the command line:

    zlib:       1.2.8-0

Now you have a software environment sandbox created with Python 3.4 and cx_freeze.

Conda automatically upgrades to unwanted version#

When making a Python package for an app, you create an environment for the app from a file req.txt that sets a certain version, such as python=2.7.9. However, when you conda install your package, it automatically upgrades to a later version, such as 2.7.10.


If you make a conda package for the app using conda-build, you can set dependencies with specific version numbers. The requirements lines that say - python could be - python ==2.7.9 instead. It is important to have 1 space before the == operator and no space after.


Exercise caution when coding version requirements.

Conda upgrade error#


Downgrading conda from 4.6.1 to 4.5.x and then trying to conda install conda or conda upgrade conda will produce a solving and upgrade error similar to the following:

Solving environment: failed
CondaUpgradeError: This environment has previously been operated on by a conda version that's newer than the conda currently being used. A newer version of conda is required.
target environment location: /opt/conda
current conda version: 4.5.9
minimum conda version: 4.6


Change the .condarc file. Set the parameter by editing the .condarc file directly: allow_conda_downgrades: true in conda version 4.5.12. This will then let you upgrade. If you have something older than 4.5.12, install conda 4.6.1 again from the package cache.

EXAMPLE: If my conda info says package cache : /opt/conda/pkgs and my Python version is 3.7, then on the command line, type conda install /opt/conda/pkgs/conda-4.6.1-py37_0.tar.bz2 to resolve the issue.

ValidationError: Invalid value for timestamp#


This happens when certain packages are installed with conda 4.3.28, and then conda is downgraded to 4.3.27 or earlier.


See conda/conda#6096.

Unicode error after installing Python 2#

Example: UnicodeDecodeError: 'ascii' codec can't decode byte 0xd3 in position 1: ordinal not in range(128)


Python 2 is incapable of handling unicode properly, especially on Windows. In this case, if any character in your PATH env. var contains anything that is not ASCII then you see this exception.


Remove all non-ASCII from PATH or switch to Python 3.

Windows environment has not been activated#


You may receive a warning message if you have not activated your environment:

This Python interpreter is in a conda environment, but the environment has
not been activated. Libraries may fail to load. To activate this environment
please see


If you receive this warning, you need to activate your environment. To do so on Windows, on a terminal via PowerShell or the Command Prompt, run: call <your anaconda/miniconda install location>\Scripts\activate base.

The system cannot find the path specified on Windows#


PATH does not contain entries for all of the necessary conda directories. PATH may have too many entries from 3rd party software adding itself to PATH at install time, despite the user not needing to run the software via PATH lookup.


Strip PATH to have fewer entries and activate your environment.

If there's some software that needs to be found on PATH (you run it via the CLI), we recommend that you create your own batch files to set PATH dynamically within a console session, rather than permanently modifying PATH in the system settings.

For example, a new conda prompt batch file that first strips PATH, then calls the correct activation procedure could look like:

call “<miniconda/anaconda root>\Scripts\activate”

If you need to run 3rd party software (software other than Windows built-ins and Anaconda) from this custom conda prompt, then you should add those entries (and only those strictly necessary) to the set PATH entry above. Note that only the quotes wrapping the entire expression should be there. That is how variables are properly set in batch scripts, and these account for any spaces in any entries in PATH. No additional quotes should be within the value assigned to PATH.

To make 3rd party software take precedence over the same-named programs as supplied by conda, add it to PATH after activating conda:

call “<miniconda/anaconda root>\Scripts\activate”
set “PATH=<3rd-party-entries>;%PATH%”

To make conda software take precedence, call the activation script last. Because activation prepends the conda environment PATH entries, they have priority.

call “<miniconda/anaconda root>\Scripts\activate”
