Cannot find module ember-cli/lib/broccoli/ember-app error in monorepo

[tomwayson]

After installing this into my ember app I get the following error when running ember asset-sizes:

Cannot find module '/Users/tom/<monorepo-root>/packages/<ember-app>/node_modules/ember-cli/lib/broccoli/ember-app'


Stack Trace and Error Report: /var/folders/_6/dgtlmj695fv5yds8f5hwvcbs8snz_f/T/error.dump.e5067a82d42b320f08aa37979af1831a.log
An error occurred in the constructor for ember-cli-asset-sizes-shim at /Users/tom/<monorepo-root>/node_modules/ember-cli-asset-sizes-shim

Note that my app is in a monorepo using yarn workspaces, so I have to use yarn add ember-cli-asset-sizes-shim and then ember generate ember-cli-asset-sizes-shim to install the addon, and that also returns the above error.

It looks like the error comes from these hardcoded paths:

ember-cli-asset-sizes-shim/index.js

Lines 81 to 82 in 1c7d803

	var pathToApp = path.join(this.project.root, 'node_modules/ember-cli/lib/broccoli/ember-app');
	var pathToAddonModel = path.join(this.project.root, 'node_modules/ember-cli/lib/models/addon');

Those would probably need to use require.resolve() in order to work in a monorepo.
