Apparrently I'm not the first one having problems with ansible -> pynacl -> sphinx, but I have no clue how to fix it right now.

this seems to be it:

  overrides = poetry2nix.overrides.withDefaults (final: prev: let
    rm.lists = lists: old: builtins.mapAttrs (name: value: lib.subtractLists value old."${name}") lists;
    modified = pkg: fns: pkg.overridePythonAttrs (oldAttrs: lib.pipe oldAttrs (builtins.map (fn: entry: entry // (fn entry)) fns));
  in
    builtins.mapAttrs (name: modified prev."${name}") {
      pynacl = [
        (rm.lists {nativeBuildInputs = with final; [sphinxHook];})
        (rm.lists {outputs = ["doc"];})
      ];
      pyjwt = [
        (rm.lists {nativeBuildInputs = with final; [sphinxHook sphinx-rtd-theme];})
        (rm.lists {outputs = ["doc"];})
      ];
    });

        (rm.lists {outputs = ["doc"];})
      ];
    });

basically I'm dropping doc output and a single nativeBuildInputs entry from both pyjwt and pynacl packages

{pkgs}:
let
  poetry2nix = import (
    builtins.fetchTarball {
      name = "poetry2nix-2024.8.2346599";
      url = "https://github.com/nix-community/poetry2nix/archive/7619e43c2b48c29e24b88a415256f09df96ec276.tar.gz";
      sha256 = "10nf9213h7vkzrqhrgk88r5sd2rq19cvdpnn59f65ifak790sgc0";
    }
  ) {
    inherit pkgs;
  };
in
  poetry2nix.overrideScope (finalPoetry2nix: prevPoetry2nix: {
    defaultPoetryOverrides = prevPoetry2nix.defaultPoetryOverrides.extend (final: prev: {
      gdal = prev.gdal.overridePythonAttrs (oldAttrs: {
        nativeBuildInputs = (oldAttrs.nativeBuildInputs or []) ++ [final.numpy];
      });
    });
  })

results in "error: value is null while a set was expected"

How can I reproduce your issue?

Yep, it's definitely something to do with the wrong Python version - I see mention of Python 3.12 in pre-commit output, and both mypy and pylint complain about missing libraries which are installed in the poetry2nix package set. Also:

❯ type -a python
python is /nix/store/d6cy7nfpwjppghqg3mav9537ypl6ww82-python3-3.11.9-env/bin/python
python is /nix/store/pgb120fb7srbh418v4i2a70aq1w9dawd-python3-3.12.5/bin/python

Hey so I just got into nix flakes and I'm trying to make the following flake:

{
  description = "A very basic flake";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
    poetry2nix.url = "github:nix-community/poetry2nix";
  };

  outputs = { nixpkgs, ... } @ inputs:
  let
    pkgs = nixpkgs.legacyPackages.aarch64-darwin;
    poetry2nix = inputs.poetry2nix.lib.mkPoetry2Nix { inherit pkgs; };
    pythonEnv = poetry2nix.mkPoetryEnv {
        python = pkgs.python311;
        projectDir = ./.;
    };
  in 
  {
      devShells.aarch64-darwin.default = pkgs.mkShell {
          packages = [ pkgs.python311 pkgs.poetry pythonEnv ];
      };
  };
}

But I am getting this error:

In reply to @adis:blad.is
It's probably a flake thing: Add poetry.lock to git.

In reply to @rpop0:matrix.org
What would be the alternative? nix-shell?

In reply to @rpop0:matrix.org
So just to understand, for example in a project when using a flake that would be for setting up a more general environment to be used by everyone. On the other hand, if I need something set up just for myself (Or I'm the only one interested in using nix), a nix-shell would be the better solution?
