title: Ng-bootstrap Import Error Angular 2
body: <p>I try to run ng-bootstrap for angular 2 and I receive an error to install ng-bootstrap. I believe that is a path problem.
  This 404 error occur when i try to access page, and on start npm.
  When angular ng-bootstrap try to load I receive a 404 error on import module:</p>
  
  <pre><code>[1] 16.08.20 20:01:00 404 GET /@ng-bootstrap/ng-bootstrap
  </code></pre>
  
  <p>But this module is inside node_modules. Thanks</p>
