pkg_resources: Wrong exception raised on parse error #2244
Description
Due to #2137 parse errors raise pkg_resources.extern.packaging.requirements.InvalidRequirement instead of packaging.requirements.InvalidRequirement.
I believe this is happening because pkg_resources imports the vendored packaging.requirements module.
Reproducer:
from pkg_resources import Requirement from packaging.requirements import InvalidRequirement from pkg_resources.extern.packaging.requirements import InvalidRequirement as ExternInvalidRequirement try: Requirement.parse(".") except InvalidRequirement as err: print(type(err)) except ExternInvalidRequirement as err: print(type(err))$ python test.py <class 'pkg_resources.extern.packaging.requirements.InvalidRequirement'>
