qutebrowser: ModuleNotFoundError: No module named 'nacl' when using keepassxc userscript

Describe the bug

Hi guys, I met the error when I was trying to use the keepassxc userscript
I used a walk-around that given by Deepseek which is able to add the missing pynacl package:

    qutebrowser = prev.qutebrowser.overrideAttrs (oldAttrs: {
      postFixup =
        (oldAttrs.postFixup or "")
        + ''
          wrapProgram $out/bin/qutebrowser \
            --set PYTHONPATH "${final.python312.withPackages (ps: [ps.pynacl])}/lib/python3.12/site-packages"
        '';
    });

Steps to reproduce

1. Install the 3.4.0 qutebrowser
2. Install keepassxc and enable the browser integration.
3. add keepassxc userscript and its keybinds.
4. Try to trigger the userscript to auto-fill credentials.

Expected behaviour

add the missing pynacl package to qutebrower pythonPath.

pynacl is already in the PYTHONPATH of qutebrowser and this userscript is also built-in.
I'm not sure what you're doing: it seems like you downloaded it from a third-party repository and placed it in your home. If that's the case, It's surely not going to work.

Try to just add this to your config: config.bind('something', 'spawn --userscript qute-keepassxc').

Sorry for being foolish, you are correct. Thank you for helping, I'll close this one.

No problem. Does it work now?
