"No matching distribution found" when building Nix shell about platformdirs HOT 10 CLOSED

https://github.com/platformdirs/platformdirs/blob/main/src/platformdirs/__init__.py#L19-L28 seems the latest release can't have this issue

from platformdirs.

Sounds to me like a feature request. How do you detect nix? We should not assume UNIX just because everything else failed 🤷‍♂️

from platformdirs.

I don't know enough about poetry2nix, Python packaging or platformdirs to answer that. How does platformdirs (or pip?) detect the platform?

from platformdirs.

I'm trying to install the latest release:

ERROR: Could not find a version that satisfies the requirement platformdirs>=2.2.0 (from pylint==2.10.2) (from versions: none)
ERROR: No matching distribution found for platformdirs>=2.2.0 (from pylint==2.10.2)

Please reopen.

We have no platform specifier in our setup.cfg either, so the problem doesn't seem to be with us.

I'm having no problem installing hundreds of other packages though :)

I'll have a dig around the pylint dependency spec, maybe the issue's there. Update: Nope, looks legit.

from platformdirs.

I'm happy to address it if you can point out what we're doing wrong, but I don't have access to this restrictive environment, so can't tell.

In case you have time, here's how to reproduce on any Linux:

Prerequisites: Nix and Poetry

cd "$(mktemp --directory)"
poetry init --name=test --author="Me <${USER}@${HOSTNAME}>" --python=^3.9 --dependency='virtualenv=*' --license=AGPLv3+ --no-interaction
poetry lock
cat > shell.nix <<'EOF'
let
  pkgs = import <nixpkgs> { };
  poetryEnv = pkgs.poetry2nix.mkPoetryEnv {
    python = pkgs.python39;
    projectDir = ./.;

    overrides = pkgs.poetry2nix.overrides.withDefaults (self: super: {
        backports-entry-points-selectable = super.backports-entry-points-selectable.overridePythonAttrs (old: {
          postPatch = ''
            substituteInPlace setup.py --replace \
              'setuptools.setup()' \
              'setuptools.setup(version="${old.version}")'
          '';
        });
      }); 
  };
in
pkgs.mkShell {
  buildInputs = [
    poetryEnv
  ];
}
EOF
nix-shell

The output includes:

ERROR: Could not find a version that satisfies the requirement platformdirs<3,>=2 (from virtualenv==20.7.2) (from versions: none)
ERROR: No matching distribution found for platformdirs<3,>=2 (from virtualenv==20.7.2)

It is, however, very interesting that my first attempt, where I initialized Poetry with --dependency='platformdirs=*' rather than the virtualenv package it worked perfectly. So maybe the problem is at the virtualenv side.

Can you provide a pure pip non poetry example, otherwise might be a poetry bug.

from platformdirs.

It doesn't seem to be a Poetry bug, because a simple poetry install in the same directory does work. Which points even stronger towards it being a poetry2nix issue :/
