title: Error during launch of an Android emulator
body: <p>I don't understand why I have this problem when I launch the emulator.</p>
  
  <pre><code>warning: the transform cache was reset.
  Loading dependency graph, done.
  error: bundling failed: Error: Unable to resolve module `react` from `/Users/myname/Sites/Project/App.js`: Module `react` does not exist in the Haste module map
  
  This might be related to https://github.com/facebook/react-native/issues/4968
  To resolve try the following:
    1. Clear watchman watches: `watchman watch-del-all`.
    2. Delete the `node_modules` folder: `rm -rf node_modules &amp;&amp; npm install`.
    3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
    4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.
  </code></pre>
  
  <p>I start the server with <code>npm start -- --reset-cache</code> command but it doesn't work. And also I tried to follow the above instruction.
  How can I do?</p>
  
  <p>I don't believe that it is a code problem, I update my Android Studio and install a component (react native elements) and now it doesn't work anymore.
  Some help?</p>
