title: React Native starter project bundling fails with Unexpected Token error
body: <p>I'm trying to create my first React Native app for Android using the instructions on <a href="https://facebook.github.io/react-native/docs/getting-started.html" rel="noreferrer">https://facebook.github.io/react-native/docs/getting-started.html</a>. After setting up the dependencies and connecting my Android device, I ran</p>
  
  <pre><code>react-native init app
  cd app
  react-native run-android
  </code></pre>
  
  <p>This starts the React Packager, which fails to bundle with this error:</p>
  
  <blockquote>
    <p>error: bundling failed: "TransformError: /Users/luky/dev/app/index.android.js: Unexpected token ) (While processing preset: \"/Users/luky/dev/app/node_modules/babel-preset-react-native/index.js\")"</p>
  </blockquote>
  
  <p>I am using:</p>
  
  <ul>
  <li>OSX El Capitan 10.11.6. </li>
  <li>node version 6.9.2 </li>
  <li>react-native version 0.47.1.</li>
  </ul>
  
  <p>I pushed my generated project, including node_modules, to Github in case it helps: <a href="https://github.com/luky1971/react-native-app" rel="noreferrer">https://github.com/luky1971/react-native-app</a></p>
  
  <p>Does anyone know why I might be getting an Unexpected token error? Any help would be greatly appreciated!</p>
