Attributes

VALID_KEYS

VALID_KEYS = ('name', 'dependencies', 'prefix', 'channels', 'variables')

validate_keys(data, kwargs)

Check for unknown keys, remove them and print a warning.

load_from_directory(directory)

from_environment(name, prefix, no_builds=False, ignore_channels=False, from_history=False)

Get environment object from prefix

Parameters

• name -- The name of environment

• prefix -- The path of prefix

• no_builds -- Whether has build requirement

• ignore_channels -- whether ignore_channels

• from_history -- Whether environment file should be based on explicit specs in history

class Dependencies(raw, *args, **kwargs)

Bases: dict

dict() -> new empty dictionary dict(mapping) -> new dictionary initialized from a mapping object's

(key, value) pairs

dict(iterable) -> new dictionary initialized as if via:

d = {} for k, v in iterable:

d[k] = v

dict(**kwargs) -> new dictionary initialized with the name=value pairs

in the keyword argument list. For example: dict(one=1, two=2)
