I am trying to setup a “Hello Word” Python project as Nix flake. Full source can be found at:
Everything works, except that “nix develop” fails to execute setuptoolsShellHook due to not finding pip. As far as I understand the situation, setuptoolsShellHook tries to install the project with pip install -e, so that I end up with an editable install of the project. However, that fails due to the search for pip running into an error.
Adding pip as buildInputs or "propagatedBuildInputs` didn’t have any effect.
Am I doing something wrong or is this a bug?
Steps to reproduce the problem:
git clone https://github.com/grumnix/hello-python.git
cd hello-python/
nix develop .
Error message:
$ nix develop .
