As a new comer to ember.js, I find this troubleshooting for bootstraping new apps is useful.
If you run `ember serve` and something weird happen to your package dependencies try to clear npm cache
`npm cache clear`
And install the dependencies again
`npm install — verbose`
Verbose mode can be helpful.
If you run `ember serve` and ENOSPC error raised please take a look at here https://github.com/ember-cli/ember-cli#problems
