2018-03-19 pip 9.0.2 and issue with pip._vendor.urllib3.contribΒΆ
pip was recently updated and the new version produces a weird error:
KeyError: 'pip._vendor.urllib3.contrib'
The error happens pip/_vendor/requests/packages.py
.
It seems related to issue
5081.
The best is to keep pip 9.0.1.
:
python -m pip install pip!=9.0.2
