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
  '';
})

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
