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. )absolute_importN) get_importer)six)urllibmapfilter)utime)mkdirrenameunlinkTF)open)isdirsplit) py31compat) platformdirs) packagingzpip._vendor.packaging.versionz pip._vendor.packaging.specifiersz"pip._vendor.packaging.requirementszpip._vendor.packaging.markers)r)rzPython 3.5 or later is requiredc@eZdZdZdS) PEP440Warningza Used when there is an issue with a version or specifier not complying with PEP 440.

(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)rrUrrrrrrrks  z#ResourceManager.set_extraction_pathFcCr)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. This method is not automatically called; you must call it explicitly or register it as an ``atexit`` function if you wish to ensure cleanup of a temporary directory used for extractions.
