Hi folks, I'm struggling to define an override that will get msgpack to build on an M1 mac. It looks like poetry2nix builds a wheel that it can't then run:

  Created wheel for msgpack: filename=msgpack-1.0.2-cp37-cp37m-macosx_11_0_arm64.whl size=67561 sha256=141d4aff3d7453e3411c0ffb7daeaf68bececd4aff7054d41a616a07a9ba7036

I'm way off understanding how to fix this, although I have tried an addPoetry style override which didn't work:

    msgpack = super.msgpack.overridePythonAttrs (
      old: {
        nativeBuildInputs = (old.nativeBuildInputs or [ ]) ++ [ self.poetry-core ];
      }
    );

Can anyone offer advice? Thanks!

I tried upgrading to the 21.11 channel, but I now run into the following for uwsgi:

pip._internal.exceptions.InstallationError: Directory '.' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.

The dir that's supposedly missing the file (it's a tmp dir and I can't check) is /private/tmp/nix-build-python3.7-uwsgi-2.0.18.drv-0.

gheesh hunting this bug down almost killed me: https://github.com/nix-community/poetry2nix/issues/523

I don't think this is a bug in poetry2nix, but an unfortunate side effect of how nixpkgs python infra propagates it's dependencies.

What does which python say?

adisbladis: Ah I see, yes, makes sense that it's leaky docker-compose in nixpkgs. Should I move the bug report there?

I think so.
A quick fixup on your end could be to override docker-compose something along these lines:

docker-compose.overridePythonAttrs(old: {
  postFixup = ''
    rm $out/nix-support/propagated-build-inputs
  '';
})
