title: "react-native eject": Unrecognized command "eject"
body: <p>I am trying to recreate ios and android folders for my react-native project. As far as I know this is done with the command:</p>
  
  <pre><code>react-native eject
  </code></pre>
  
  <p>But I get the error:</p>
  
  <pre><code>error Unrecognized command "eject".
  </code></pre>
  
  <p>I am doing something wrong? How should I recreate android and ios folders?</p>
