title: can't resolve 'react' for mdl module
body: <p>Trying to build my first website with react, following along with this tutorial: <a href="https://www.youtube.com/watch?v=9AboneIxeM8&amp;t=599s" rel="nofollow noreferrer">https://www.youtube.com/watch?v=9AboneIxeM8&amp;t=599s</a></p>
  
  <p>I am trying to install and use the <a href="https://github.com/tleunen/react-mdl" rel="nofollow noreferrer">material lite module</a>, however when I start npm I get a failure to compile with the following message :</p>
  
  <p>Module not found: Can't resolve 'react' in '/Users/user/node_modules/react-mdl/lib'</p>
  
  <p>Can someone help me understand what this means and how to fix it ? I'm at a loss it seems above my skill level.</p>
