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. i ( t absolute_importN( t get_importer( t six( t urllibt mapt filter( t utime( t mkdirt renamet unlink( t open( t isdirt spliti ( t py31compat( t appdirs( t packagings pip._vendor.packaging.versions pip._vendor.packaging.specifierss" pip._vendor.packaging.requirementss pip._vendor.packaging.markersi i s Python 3.5 or later is requiredt PEP440Warningc B@ s e Z d Z RS( sa Used when there is an issue with a version or specifier not complying with PEP 440.

To allow usage of packages that explicitly require a newer version of Mac OS X, we must also know the current version of the OS.

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.
