[Bug Report] Runtime Error after running packwerk check about packwerk HOT 1 CLOSED

Hi @oskygh !

It looks like you're having some trouble setting up autoload paths to ensure that constants are properly by zeitwerk.

Packwerk assumes your rails application is already properly set up but doesn't play a role in actually setting up, so this isn't actually a bug in packwerk, but rather a configuration issue with your Rails app (as suggested by the error message).

Stimpack actually solves this issue for you – as long as your app is structured like the one in the stimpack readme (which is pretty close to what you have now – you'll just need to move the packages up a level and set packages as the root directory). You can check out the stimpack implementation to see more of how it adds the autoload paths. Alternatively if you want to manage autoload paths yourself, I'd recommend checking out the READMEs for zeitwerk and the Rails guide on autoloading, which I think is here.

Let me know if this helps solve your problem.
