KeyError: 'pip._vendor.urllib3.util.queue' on any pip command

Environment

• pip version: 10.0.1
• Python version: 3.6
• OS: Manjaro Linux

Description On any pip command, even on simply calling pip --help I get this:

Yes, it appears to be some sort of distro-based problem. Simply reinstalling pip didn’t help, but

rm -r /usr/lib/python3.6/site-packages/pip;
pacman -S python-pip --force

solved it for me. Got the idea from those two reports [1] [2].

During handling of the above exception, another exception occurred:
