Description
Environment
- pip version: 21.0.1
- Python version: 3.9.1
- OS: Windows
Description
With the latest version of packaging (vendored in 21.0.1) a DeprecationWarning is issued when parsing a "legacy version". If pip is run with warnings converted to errors, this causes a failure.
Expected behavior
No error
How to Reproduce
py -wE -m pip --version
Or to pinpoint it further,
py -wE
>>> from pip._vendor import pkg_resources
This does not happen with setuptools 52.0.0, it appears to be related to the version of setuptools (44.0.0) that we vendor.
