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
  '';
})

Hi. I'm struggling in making a development shell for my project. It fails when trying to fetch pytest. I have made a minimal example: https://github.com/martiert/poetry2nix-pytest-error

Not sure if this is a bug, or I'm doing something wrong? My ideal result of this is me being able to run python -m pytest in the shell and have it run my tests

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!

For future folks with this problem, updating to the 21.11 channel removed the error.
