Nix noob question: Way to run this directly from a private git?

[tcb678]

First, thanks for publishing and contributing to this repo.

I'm on a Darwin system and use this flake with a high degree of success locally by cloning the repo and running .#build-switch. I've made several changes to fit my environment.

When I am starting with a new system, it would be great if I could, say, run nix build or nix run directly against the git repo where I keep a copy of this. Unfortunately, there seem to be a lot of problems with this approach:

1. When doing nix run git+ssh://[email protected]/<user>/<repo>#build-switch, it says the local directory doesn't contain a flake.nix
2. When doing nix build with a similar path, Nix complains packages.aarch64-darwin.build-switch doesn't exist (and when doing a fully qualified #apps.aarch64-darwin.build-switch, it complains it sees a set but not a derivation or path)
3. nix flake show works correctly and shows the apps

A clone works fine, though. Am I missing something obvious? I don't want to start from a new template - I want to run the whole enchilada. ChatGPT suggests this is because mkApp can't expose a file system view of its outputs, but that seems a bit bogus.

Any bright ideas?
