ng serve build error after npm install
<p>I'm getting the following error in my angular2 app with cmd <code>ng serve</code> after deleting the <code>node_modules</code> directory and building it new with <code>npm install</code>.</p>

<pre><code>Error: Cannot find module 'common-tags'

<p>also <code>npm install common-tags</code> to add it manually does not work</p>
