No module hatchling trying to follow along the Tweag Video in the Poetry2nix documentation

[henrik-ch]

Is this an issue in the style of "package "X fails to build"? Maybe yes - but nothing is mentioned about it in the introduction video from Tweag with Steve Purcell. Poetry2nix: Package and deploy Python apps faster with Poetry and Nix by Tweag.

Describe the issue

Following the steps of the video - everything goes well up until time 05:15 - nix-build command on the default.nix file.

The code has been added to a repo for easier access: https://github.com/henrik-ch/tweag-p2nix-video/

Additional context

As you can see on the branches of the repo - I tried various approaches to fix the issue - none of them successful.

• main branch following the given instructions as given in video - no modifications (following instructions to best abilities)
• Pinned nixpkgs to nixpkgs 22.11 - exact same result - no module named hatchling.
• Test flake used the flake init as described in the README.md - this nix build command fails with a pillow problem - see the error traceback on this branch.
• Edgecases override when opening the issue, I saw the notes in the edgecases.md file. I must admit that I don't yet understand what the override does - and I cargoculted something that is accepted as nix syntax, but I have no idea if/what effect it has. The nix-build command fails with the same error as the main branch.

I have seen in the backchat on poetry2nix Matrix channel that this module was discussed on April 19th 2023 - but I am not sure what was the outcome and action - and how to implement it on my example. https://github.com/henrik-ch/tweag-p2nix-video/blob/main/matrix-screenshot.png
