Hi, glad to find this great nix tool and find you all here. I have a quick question. I am following this blog https://www.tweag.io/blog/2020-08-12-poetry2nix/ and I enconter this error:

 error: poetry2nix is now maintained out-of-tree. Please use https://github.com/nix-community/poetry2nix/

What does this mean and how to avoid that? Thx!

This is my default.nix:

This is my default.nix updated and it still doesn't work:

{ pkgs ? import <nixpkgs> {} }:
let
  poetry2nix = pkgs.poetry2nix.override {
    poetry2nix = pkgs.nix-community.poetry2nix;
  };
in
poetry2nix.mkPoetryApplication {
  projectDir = ./.;
}

Thanks! with this config in the readme, I have got the same error.

{ poetry2nix, python3, runCommand }:
let
  env = poetry2nix.mkPoetryEnv {
    python = python3;
    pyproject = ./pyproject.toml;
    poetrylock = ./poetry.lock;
  };
in
runCommand "env-test"
{ } ''
  ${env}/bin/python -c 'import alembic'
  touch $out
''

Thanks! with this config in the readme, I have got the same error.

let
  pkgs = import <nixpkgs> {
    overlays = [
      # self & super refers to nixpkgs
      (self: super: {

        # p2self & p2super refers to poetry2nix
        poetry2nix = super.poetry2nix.overrideScope' (p2nixself: p2nixsuper: {

          # pyself & pysuper refers to python packages
          defaultPoetryOverrides = p2nixsuper.defaultPoetryOverrides.extend (pyself: pysuper: {

            my-custom-pkg = super.my-custom-pkg.overridePythonAttrs (oldAttrs: { });

          });

        });
      })

    ];
  };

in pkgs.poetry2nix.mkPoetryApplication {
  projectDir = ./.;
}

Hi. I'm getting the following error when trying to build my application via flake:

error: hash mismatch in fixed-output derivation '/nix/store/fygngq683zgps12zy1063gbq8vsjzvzm-cryptography-41.0.7-vendor.tar.gz.drv':
         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=

I read about this issue, but I'm using a flake and made sure the revision for poetry2nix in flake.lock matches the HEAD commit in the master repo. Any ideas what could be wrong?

I'd like help to understand editablePackageSources.

I've defined on my flake.nix:

        cexpl-py = (p2n.mkPoetryEnv {
          projectDir = ./.;
          editablePackageSources = {
            cexpl = ./.;
          };
          overrides = p2n-overrides;
        }).env.overrideAttrs (oldAttrs: {
          buildInputs = dependencies;
        });

and I'm able to import my package:

❯ python3
Python 3.11.6 (main, Oct  2 2023, 13:45:54) [GCC 12.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cexpl
>>> cexpl
<module 'cexpl' from '/nix/store/vj18qa9acmghnipqx98x94fqbhg1vcdq-source/cexpl/__init__.py'>
>>>

But it shows up inside the nix store, which is read-only. So, how could it be "editable"?

pip show outputs:
