This error appears starting with pip version 19.3 (detected empirically). If anyone can tell me how to fix this, then I will be VERY grateful doubly .

I really count on your help. Sincerely.

I have another solution: https://ish.app/

apk add python3 curl
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py

Everything installs great! Even nodejs, PHP, GO and others work! And even tox, virtualenv works! And even the tests pass, wow!
Just don't forget to install programs like git, there's nothing there by default.
