- reinstall_packages(args, specs: list[str], **kwargs) int#
Reinstall packages using conda install.
Helper for health fixes that need to reinstall packages.
- Parameters:
args -- Parsed arguments namespace
specs -- Package specs to reinstall
kwargs -- Override default install options (e.g., force_reinstall=True)
- clone(src_arg, dst_prefix, json=False, quiet=False, index_args=None)#
- get_revision(arg, json=False)#
- get_index_args(args) dict[str, Any]#
Returns a dict of args required for fetching an index
- Parameters:
args -- The args provided by the cli
- Returns:
dict of index args

- succeed()#
- validate_install_command(prefix: str, command: str = 'install')#
Executes a set of validations that are required before any installation command is executed. This includes:
ensure the configuration is valid
ensuring the user in not an admin
ensure the user is not forcing 32bit installs in the root prefix
- Parameters:
prefix -- The prefix where the environment will be created
command -- Type of operation being performed
- Raises:
error if the configuration for the install is bad --
- ensure_update_specs_exist(prefix: str, specs: list[str])#
Checks that each spec that is requested as an update exists in the prefix
- Parameters:
prefix -- The target install prefix
specs -- List of specs to be updated
- Raises:
CondaError -- if there is an invalid spec provided
PackageNotInstalledError -- if the requested specs to install don't exist in the prefix
- install(args, parser, command='install')#
Logic for conda install, conda update, and conda create.
- install_clone(args, parser)#
Executes an install of a new conda environment by cloning.
- install_revision(args, parser)#
Install a previous version of a conda environment
- revert_actions(prefix, revision=-1, index: conda.core.index.Index | None = None)#
- handle_txn(unlink_link_transaction, prefix, args, newenv, remove_op=False, defer_json_success=False) dict | None#
Handles executing an unlink_link_transaction, and reporting changes. If defer_json_success argument is provided, will return a dict of actions that have been taken as part of the transaction.
- Parameters:
unlink_link_transaction -- transaction to execute, output from the solver
prefix -- prefix to execute the transaction on
args -- cli args
newenv -- boolean noting that the environment is being created for the first time
remove_op -- defaults to false, boolean noting that the user is requesting to remove a package from the environment
defer_json_success -- when true, will return the set of actions executed in dict form
