title: How to run the official vue.js examples?
body: <p>I git cloned vue, cd'ed into one of the examples folder and ran <code>npm install</code>. Everything went fine, then I ran <code>npm run dev</code> and it gets stuck at this stage. Is there anything else I should do to run this locally?</p>
  
  <pre><code>npm run dev
  &gt; vue@2.4.2 dev /vue
  &gt; rollup -w -c build/config.js --environment TARGET:web-full-dev
