title: Error: Cannot find module 'semver'
body: <p>I was working on a simple Ionic App.</p>
  
  <p>Steps taken:</p>
  
  <ul>
  <li>updated ionic - OK </li>
  <li>started new project - OK </li>
  <li>created a couple of pages- OK</li>
  <li>served the app - OK</li>
  </ul>
  
  <p>but then I tried to add the android platform:</p>
  
  <blockquote>
    <p><em>ionic platform add android</em></p>
  </blockquote>
  
  <p>and got this error:</p>
  
  <blockquote>
    <p>ERROR: Cannot find module 'semver'
       at Function.Module._resolveFilename (module.js:336:15)</p>
    
    <p>Caught exception:
     undefined</p>
  </blockquote>
  
  <p>Any idea on why I'm getting this error and how to fix it?</p>
  
  <p>Thanks!</p>
