title: Use react-rails with packages that have react as dependency
body: <p>I've been playing with <code>rails-react</code> and it works great. Recently I added the <a href="https://github.com/paramaggarwal/react-dropzone" rel="nofollow noreferrer">react-dropzone</a> library in my <code>package.json</code>.</p>
  
  <p>I get the following error when I run <code>npm install</code>:</p>
  
  <p><code>npm WARN EPEERINVALID react-dropzone@3.2.2 requires a peer of react@^0.14.0 but none was installed.</code></p>
  
  <p>If I explicitly add <code>react</code> it installs everything just fine.</p>
  
  <p>However when I go into the browser, I get the following error:</p>
  
  <p><a href="https://i.stack.imgur.com/S3JBo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/S3JBo.png" alt="enter image description here"></a></p>
  
  <p>Using <code>react-rails (1.5.0)</code> and <code>"react-dropzone": "^3.2.2"</code></p>
