I'm trying to run trelby, some screenwriting software. I actually bricked my Ubuntu install when trying to set this up there because wxPython didn't install, I tried creating venvs and that didn't work either, and I ended up trying to delete Python entirely... So I ended up here.
I cloned the repo, set up a shell.nix with the required packages, and am now stuck with the same problem I had before: wxPython doesn't install.

# shell.nix

# We pin to a specific nixpkgs commit for reproducibility.

pkgs = import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/cf8cc1201be8bc71b7cbbbdaf349b22f4f99c7ae.tar.gz") {};
in pkgs.mkShell {
packages = [
(pkgs.python3.withPackages (python-pkgs: with python-pkgs; [
# select Python packages here
setuptools
wxPython
lxml
reportlab
pytest
]))
];
}
Output from attempting to run nix-shell:

Cheers!
Edit: solved! Just change the wxPython to wxpython on the shell.nix file, and probably also change the manual fetch from an outdated repo to <nixpkgs> as @Edie@hexbear.net recommended.
There are prebuilt binaries on their website, you dont have to compile trelby from source on your own.
I just mentioned docker/containers because it's a way to escape NixOS FHS incompatability and get back to a standard Linux environment.
I'm surprised that trelby isnt packaged in NixOS, maybe someone will get on that.
Yeah you're absolutely right, I had tried that website 2 days ago but my "spot the download button" skills failed and I had ended up downloading the source code; I ended up thinking the source code was all they had, no binary release.
