The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is. Do not use os.path operations to manipulate resource names being passed into the API. The package resource API is designed to work with normal filesystem packages, .egg files, and unpacked .egg files. It can also work in a limited way with .zip files and with custom PEP 302 loaders that support the ``get_data()`` method. This module is deprecated.

Unless `replace_conflicting=True`, raises a VersionConflict exception if any requirements are found on the path that have the correct name but the wrong version. Otherwise, if an `installer` is supplied it will be invoked to obtain the correct version of the requirement and activate it. `extras` is a list of the extras to be used with these requirements. This is important because extra requirements may look like `my_req; extra = "my_extra"`, which would otherwise be interpreted as a purely optional requirement.

If `full_env` is not supplied, one is created automatically from the ``WorkingSet`` this method is called on, which will typically mean that every directory on ``sys.path`` will be scanned for distributions. `installer` is a standard installer callback as used by the ``resolve()`` method. The `fallback` flag indicates whether we should attempt to resolve older versions of a plugin if the newest version cannot be resolved. This method returns a 2-tuple: (`distributions`, `error_info`), where `distributions` is a list of the distributions found in `plugin_env` that were loadable, along with any other distributions that are needed to resolve their dependencies. `error_info` is a dictionary mapping unloadable plugin distributions to an exception instance describing the error that occurred.

If a suitable distribution isn't active, this method returns the newest distribution in the environment that meets the ``Requirement`` in `req`.

Resource providers should call this method ONLY after successfully extracting a compressed resource.

If you do not call this routine before any extractions take place, the path defaults to the return value of ``get_default_cache()``. (Which is based on the ``PYTHON_EGG_CACHE`` environment variable, with various platform-specific fallbacks. See that routine's documentation for more details.) Resources are extracted to subdirectories of this path based upon information given by the ``IResourceProvider``. You may set this to a temporary directory, but then you must call ``cleanup_resources()`` to delete the extracted files when done. There is no guarantee that ``cleanup_resources()`` will be able to remove all extracted files. (Note: you may not change the extraction path for a given resource manager once resources have been extracted, unless you first call ``cleanup_resources()``.) z5Can't change extraction path, files already extractedN)r?rErB©rr³rrrr[7sz#ResourceManager.set_extraction_pathFcCsdS)aB Delete all extracted resource files and directories, returning a list of the file and directory names that could not be successfully removed. This function does not have any concurrency protection, so it should generally only be called when the extraction path is a temporary directory exclusive to a single process.
