If you've just made a new Ember-CLI project and run `ember test` or `ember serve` you're going to 
see this error message:

version: 0.1.11
Could not find watchman, falling back to NodeWatcher for file system events
Build failed.

It's because you dont have a Git repo initialized. 

Do `git init . && git add . && git commit -m "Initial commit"` and 
everything will be fine. As far as I can see this bug has just been 
addressed and will be pushed out soon.
