title: Ionic serve not working with ionic2
body: <p>I have started a clean project with ionic2 based on tabs template, by following the next steps:</p>
  
  <pre><code>$ ionic start &lt;myapp&gt; --v2
  $ cd &lt;myapp&gt;
  $ ionic serve
  </code></pre>
  
  <p>Then the output from <code>ionic serve</code> is just:</p>
  
  <pre><code>&gt; ionic-hello-world@ ionic:serve /home/luan/&lt;myapp&gt;
  &gt; ionic-app-scripts serve "--v2" "--address" "0.0.0.0" "--port" "8100" "--livereload-port" "35729"
  </code></pre>
  
  <p>If I try to open <code>localhost:8100</code> there's no response.</p>
  
  <p>The files and code of the project are just the same as one using tabs template, but it's just don't wonking.
  Could someone help?</p>
