ember-cli: Cannot read property '_watchmanInfo' of undefined

After updating to ember-cli-2.6.0-beta.3 I’m getting this error when starting an app:

Cannot read property '_watchmanInfo' of undefined

If anyone else has this problem, try to isolate the offending addon, and check whether it has ember-cli-htmlbars in addon’s package.json dependencies instead of devDependencies, maybe also whether it overrides init() in index.js while forgetting to call super(), as was the case for me. Hope it helps.

@cesarizu ember-cli-font-awesome is deprecated, trying it with ember-font-awesome works for me. Please update to that and everything should work!

@nathanhammond I think I’ve narrowed the error down to ember-cli-font-awesome. With a new project, installing that addon using ember install ember-cli-font-awesome and then running with ember serve gives that error.
