When I set editablePackageSources.myapp = ./src, this should work right? So that when I edit ./src/myapp/test.py, I thought I should be able to see that change when I run python -m myapp.test, but the same code is executed for me.

Update: I've created a PR with the relevant failing test.

Anyone experienced "missing attribute" error recently? Wrt. `inputs.flake-utils.lib.eachDefaultSystem`. Once I made it follow my existing `flake-utils` input I get nix complaining about line 82 in poetry2nix's `flake.nix` on current `master` (`5a62572`).

Here's my flake.nix, stripped of non-Nix/poetry2nix related sturr:

{
  description = "A Nix-flake for poetry based python development ";

  inputs = {
    flake-utils.url = "github:numtide/flake-utils";
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    poetry2nix = {
      url = "github:nix-community/poetry2nix";
      inputs.nixpkgs.follows = "nixpkgs";
      inputs.flake-utils.follows = "nixpkgs";
    };
  };

  outputs = {
    self,
    ...
  } @ inputs:
    inputs.flake-utils.lib.eachDefaultSystem (system: let
      pkgs = import inputs.nixpkgs {localSystem = {inherit system;};};
      inherit (inputs.poetry2nix.lib.mkPoetry2Nix { inherit pkgs; }) mkPoetryApplication;
      myapp = mkPoetryApplication {projectDir = self;};
    in {
      devShells.default = pkgs.mkShell {
        inputsFrom = [myapp];
        packages = with pkgs; [

              ]
            )
          )
        ];

        shellHook = ''

      packages.default = myapp;

You could try nixpkgs.follows = "poetry2nix/nixpkgs"; rather than the other way around.

Thanks for taking a look @truh! Huhm...
I agree that there's a channel mismatch between the two...

But how do you figure it's related to the error message? I don't see anywhere there might be a reference to a flake-utils version missing https://github.com/numtide/flake-utils?tab=readme-ov-file#eachdefaultsystem--system---attrs.

  `inputs.flake-utils.follows = "nixpkgs";` this shouldn't follow nixpkgs

I'm trying to build an older version of poetry, specifically version 1.4.2. I have this derivation:

{ fetchFromGitHub, poetry2nix }:
poetry2nix.mkPoetryApplication {
    projectDir = fetchFromGitHub {
        owner = "python-poetry";
        repo = "poetry";
        rev = "1.4.2";
        hash = "sha256-AiRQFZA5+M1niTzj1RO2lx0QFOMmSzpQo1gzauyTblg=";
    };
}

The derivation builds fine. However, the resulting package depends on the build module version 1.0.3. This is a problem, since the poetry.lock from that version of poetry requires build version 0.10. As a result, the poetry package doesn't work since that version of poetry breaks with that version of the build package.

I have attempted to override the build package version:

{ fetchFromGitHub, poetry2nix }:
poetry2nix.mkPoetryApplication {
    projectDir = fetchFromGitHub {
        owner = "python-poetry";
        repo = "poetry";
        rev = "1.4.2";
        hash = "sha256-AiRQFZA5+M1niTzj1RO2lx0QFOMmSzpQo1gzauyTblg=";
    };
    overrides = poetry2nix.defaultPoetryOverrides.extend (final: prev: {
        build = prev.build.overridePythonAttrs (old: {
            version = "0.10.0";
            src = fetchFromGitHub {
                owner = "pypa";
                repo = "build";
                rev = "0.10.0";
                hash = "sha256-kXFrfTb7+68EV+gSENL81IFSR+ue7Fl6R2gsuFFBJhI=";
            };
        });
    });
}

But, when I do that, I get a build error:

I've tried searching the edgecases documentation but didn't find anything that seems to explain what I should do in this case.

Anyway, I was about to open an issue, but saw that it asked that I first post problems to the Matrix chat and I was wondering if anyone had any idea what I was doing wrong or if I should open up an issue.

Thanks in advance!
