title: unable to resolve module `@expo/vector-icons`
body: <p>Im not sure why I'm getting this error:</p>
  
  <pre><code>Unable to resolve module `@expo/vector-icons` from `...(directory path here)...` : Module does not exist in the module pack
  </code></pre>
  
  <p>I have tried the following things suggested on other forums/sites:</p>
  
  <ol>
  <li>Clear watchman watches</li>
  <li>Deleting the node_modules folder</li>
  <li>Reset packager cache</li>
  </ol>
  
  <p>package.json</p>
  
  <pre><code>{
    "name": "app name",
    "version": "0.0.0",
    "description": "Hello Expo!",
    "author": null,
    "private": true,
    "main": "node_modules/expo/AppEntry.js",
    "dependencies": {
