title: Can't add Android platform and build ionic project anymore?
body: <p>So I wanted to start a new ionic project by writing:
  <code>ionic start Ionic1 blank</code></p>
  
  <p>After that I moved to that new directory and wanted to add android platform:
  <code>ionic platform add android</code></p>
  
  <p>I then got this error:</p>
  
  <blockquote>
    <p>Error: Failed to fetch platform android
    Probably this is either a connection problem, or platform spec is incorrect.
    Check your connection and platform name/version/URL.
    Error: EACCES: permission denied, open '/home/think/.cordova/lib/npm_cache/cordova-android/4.1.1/package/.npmignore'</p>
  </blockquote>
  
  <p>I don't know why this happens. I tried these:</p>
  
  <p>1) change the permision with </p>
  
  <pre><code>chmod 744 /home/think/.cordova/lib/npm_cache/cordova-android/4.1.1/package/.npmignore
  </code></pre>
  
  <p>2) uninstalled and installed nodejs, cordova, ionic, etc.</p>
  
  <p>3) Executed with <code>sudo ionic platform add android</code> (but "<code>sudo</code>" is not necessary i think since I added android platform before in other projects without having to write "<code>sudo</code>" )</p>
  
  <p>Still it's somehow not possible to add a platform.</p>
  
  <p>I'm on ubuntu 14.04 LTS. I have android SDK manager installed.</p>
  
  <p>I can build and run my other ionic projects that I created earlier. But since yesterday I can't build new projects anymore. It happened when I iupdated to ionic 1.7.13. I tried to downgrade ionic to an earlier version but that wouldn't solve the issue either.</p>
