title: Cannot find type definition file for 'ramda'
body: <p>I have a project with <code>Ionic</code> 2 &amp; <code>Angular</code> 2.</p>
  
  <p>I use RamdaJS in my code, this is perfectly working with these commands:</p>
  
  <ul>
  <li><code>ionic serve</code> </li>
  <li><code>ionic cordova build android</code> </li>
  <li><code>ionic cordova run android</code></li>
  </ul>
  
  <p>But when I try to execute this command: <code>ionic cordova build android --prod --release</code>, I got an error about Ramda and Type.</p>
  
  <p>See a part of my <code>package.json</code>:</p>
