Doesn't work with docker alpine image: No matching distribution found for py-spy

[marcstreeter]

using python:3.6-alpine image (running Python 3.6.6) and getting the following behavior when attempting to install py-spy

pip install py-spy
Could not find a version that satisfies the requirement py-spy (from versions: )
No matching distribution found for py-spy

works with regular python image, it's the alpine images it doesn't work with.

So, alpine python opts out of the manylinux1 wheels: pypa/pip#3969 (comment) . It seems like it's because of a compatibility issue with glibc instead of musl libc that they use.

Its' possible to get py-spy to install on alpine docker linux by following the steps there

/ # echo 'manylinux1_compatible = True' > /usr/local/lib/python3.6/site-packages/_manylinux.py
/ # pip install py-spy

But it still doesn't work because of the glibc issues =(.

I'm switching over from using glibc as a dynamic lib, to using musl as a static library to get around some other issues, and I believe once that change has been made this should work.

I pushed the musl libc changes out with v0.1.5 and tested with python:3.6-alpine docker image. With setting that manylinux1 flag everything seems to work when installing from pip (alternatively you can also install using cargo).

Sorry to dig this old issue up. You might want to suggest to users that they rm /usr/local/lib/python3.7/site-packages/_manylinux.py after doing this. Otherwise, subsequent pip install usually end up with lots of ldd errors.

Alternatively, maybe the pip package can distribute binaries that are musl built instead (if that's not already the case).

    git clone https://github.com/benfred/py-spy.git \
    && cd py-spy \
    && pip install --editable . --verbose \
    && cd ..

seems to work as well (without messing with _manylinux.py). Hard to say which is preferable.
