ERROR: npm failed to install dependencies

Here are a few things you can try, depending on the error:
1. Set `makeCacheWritable = true`
  Note that this won't help if npm is complaining about not being able to write to the logs directory -- look above that for the actual error.
2. Set `npmFlags = [ "--legacy-peer-deps" ]`

Lily Foster: I've tested manually marp-cli from your Nix code and it works well 🎉 I've pushed a PR. Are you the one who can approve and merge? https://github.com/NixOS/nixpkgs/pull/248107

Ambroisie: Does pnpm-lock-export need internet access and does it have a reproducible output?

1. I don't think so
2. I think so
   But I haven't checked either
