I’m currently trying to package this templating tool, Copier, as a flake: GitHub - copier-org/copier: Library and command-line utility for rendering projects templates.
My general Python experience is limited, and my python-package-management experience is effectively nil.
I had issues using poetry2nix so someone on the discord suggested I just use buildPythonPackage with format = "pyproject". I’m trying to build the dependencies that aren’t available in nix with the very same function (which you will see in the flake below), however, whenever I try to nix run . I get an infinite recursion error. The current error occurs when it tries to evaluate the iteration-utilities attr.
Is there an obvious culprit? Maybe in how I access buildPythonPackage?
