Impossible to install wheel on alpine

[RCheese]

pip version

21.0.1

Python version

3.8

OS

alpine 3.12

Additional information

No response

Description

since pip 20.3 and PEP 600 package with manylinux*_compatible tags has no chance to be installed under alpine. Now PyPI has too few packages with manylinux_alpine compatible tags, but older packets were good. e.g. orjson or brotlipy were broken. PEP 600 doesn't provide clear information about right way to live now

Expected behavior

(e.g.) orjson successfully installed (by latest *.whl)

How to Reproduce

docker run -it python:3.8-alpine ash
echo 'manylinux2014_compatible = 1' > /usr/local/lib/python3.8/_manylinux.py
pip install orjson

Output

Alpine Linux uses musl, while manylinux wheels are based on glibc, so you can't install manylinux wheels on Alpine. They won't work even if you managed to put the files inside your system.

[RCheese]

Yes! But it worked before! And issues on supports it in packages repos estimates in thousands

[RonnyPfannschmidt]

@RCheese it worked by random luck and you are very lucky nothing horrible happened, pip just got better and now things that where never supported to begin with, don't install, it's time for you to fix your build
