  <p>The error originates on line 62 of react-native-camera <code>index.js</code> which is calling <code>NativeModules.CameraManager</code>. Does this have something to do with expo not having access to some native APIs?</p>
  
  <p>Steps already taken:</p>
  
  <ul>
  <li>react-native link react-native-camera</li>
  <li>watchman watch-del-all</li>
  <li>rm -rf node_modules &amp;&amp; npm install</li>
  <li>rm -fr $TMPDIR/react-*</li>
  <li>npm start -- --reset-cache</li>
  </ul>
  
  <p>Restarting the build</p>
  
  <p>I also created a regular react native app via <code>react-native init</code> and was able to properly set up react-native-camera without any issues.</p>
