pip exception: AttributeError: 'NoneType' object has no attribute 'startswith'

Question

When I use pip to install some packages, I always get the same exception:

PS C:\\Users\\84682\\Desktop> pip install         


        

Answer 1

I got the same error message trying to run pip from a docker compose. The underlying problem which caused the error was that I had defined my proxy setting with one slash too few: http:/myproxy... .

Then after correcting that bug everything worked.

I hope this helps somebody who has the same problem.
