title: Module `expo` does not exist in the Haste module map
body: <p>I am trying to create a react-native bundle and getting the following error:</p>
  
  <pre><code>Unable to resolve module `expo` from `C:\Users\&lt;User&gt;\Projects\myProject\src\HomeScreen\HomeScreen.js`: Module `expo` 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 star
  t -- --reset-cache`.  4. Remove haste cache: `rm -rf /tmp/haste-map-react-native
  -packager-*`.
  </code></pre>
  
  <p>Any clue how do I install the expo module. Tried doing <code>npm --proxy=http_proxy_server:proxy_port install --save expo</code> but it fails with following error:</p>
