Cannot find peerDependency (miragejs) with importSync

[jrjohnson]

Getting the error Could not find module miragejs imported from (require) with miragejs in the devDependencies as well as peerDependencies. I created a reproduction and you can see the error at https://github.com/jrjohnson/test-miragejs-import/runs/4962685303?check_suite_focus=true#step:6:19 this is a new addon with miragejs installed and then used like:

if (macroCondition(dependencySatisfies('miragejs', '*'))) {
  const { Response } = importSync('miragejs');
  console.log(Response);
}

Not sure if I'm using this wrong or there is an issue with this specific import.

You need to install ember-auto-import as a dependency when you import npm packages in addon code. After doing that (and returning Response from the util,) the test doesn't seem to fail anymore (at least for me locally).

Thank you so much @Windvis! Really really appreciate the help here. It seems maybe intuitive, but I would never have tried that assuming that importSync would bring it's own stuff and not rely on EAI. You've gotten me through a very frustrating situation and I can't thank you enough. I'm going to touch up the docs if I have a moment, but go ahead and close this issue.
