title: Ionic RC0: error TS4053: Return type of public method from exported class has or is using name 'Entry' from external module
body: <p>I am upgrading my project to Ionic RC0 from Beta 11 by creating a new RC0 project and following the instructions in <a href="https://github.com/driftyco/ionic/blob/master/CHANGELOG.md" rel="nofollow">https://github.com/driftyco/ionic/blob/master/CHANGELOG.md</a></p>
  
  <p>I have sorted out most of the issues, except for couple. One among them is following errors:</p>
  
  <pre><code>error TS4053: Return type of public method from exported class has or is using name 'Entry' from external module "/Users/saiy2k/projects/ionic/gr/node_modules/ionic-native/dist/es5/plugins/file" but cannot be named
  
  error TS4053: Return type of public method from exported class has or is using name 'FileError' from external module "/Users/saiy2k/projects/ionic/gr/node_modules/ionic-native/dist/es5/plugins/file" but cannot be named.
  
  error TS4053: Return type of public method from exported class has or is using name 'DirectoryEntry' from external module "/Users/saiy2k/projects/ionic/gr/node_modules/ionic-native/dist/es5/plugins/file" but cannot be named.
  </code></pre>
  
  <p>I Installed the File cordova plugin, but still.</p>
  
  <p>Any help is appreciated</p>
