The loader.js addon is missing
<p>I have cloned my ember project, use following commands</p>

<pre><code>npm install
bower install

ember build
</code></pre>

<p>and got this message</p>

<blockquote>
  <p>DEPRECATION: Brocfile.js has been deprecated in favor of
  ember-cli-build.js. Ple ase see the transition guide:
  <a href="https://github.com/ember-cli/ember-cli/blob/master" rel="nofollow">https://github.com/ember-cli/ember-cli/blob/master</a>
  /TRANSITION.md#user-content-brocfile-transition. The loader.js addon
  is missing from your project, please add it to <code>package.json</code>.</p>
</blockquote>

<p>I have searched about this exception and tried to install loader.js manually, but after this another got another exception :</p>

<blockquote>
  <p>can't find module rsvp</p>
</blockquote>

<p>It seems there is some global problem in my project, I can't determine what is it.</p>

<p>And about deprecation - brocfile.js, I haven't changed it, should I?</p>
