<p>Whenever I'm trying to use MdButton in my application by importing it from angular-material as <code>import {MdButton} from '@angular2-material/button';</code> , I'm getting following error as shown below</p>

<pre><code>"NetworkError: 404 Not Found - http://localhost:3000/@angular/core.js"

<p>I couldn't see @angular folder inside node_modules. How to get that folder if required?<br>
Why it is failing?<br>
Note: My application works fine if i remove dependency from angular-material.</p>
