pkg_resources get_provider return NullProvider where use egg without source #1337
Description
if we install python egg without source, we will get _frozen_importlib.SourcelessFileLoader when call resource_isdir, and get NotImplementedError( "Can't perform this operation for unregistered loader type" )
how to solver it.
path DefaultProvider._register
before:
@classmethod def _register(cls): loader_cls = getattr( importlib_machinery, 'SourceFileLoader', type(None), ) register_loader_type(loader_cls, cls) after:
@classmethod def _register(cls): loader_cls = getattr( importlib_machinery, 'SourceFileLoader', type(None), ) register_loader_type(loader_cls, cls) loader_cls2 = getattr( importlib_machinery, 'SourcelessFileLoader', type(None), ) register_loader_type(loader_cls2, cls) then it works well.
