title: import error when using react-icons
body: <p>I have tried installing react icons, in my application I ran the npm command:</p>
  
  <pre><code>sudo npm install react-icons --save
  </code></pre>
  
  <p>I didn't get any errors, apart from some optional dependencies, that where skipped</p>
  
  <pre><code>npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 
  (node_modules/fsevents):
  npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for 
  fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: 
  {"os":"linux","arch":"x64"})
  </code></pre>
  
  <p>Whenever I try to import some of the icons, I get an error</p>
  
  <pre><code>./src/components/SkiDaysCount.js
  Module not found: Can't resolve 'react-icons/lib/md' in ' 
  '/home/kristoffer/ReactApps/navbar/src/components'
  </code></pre>
  
  <p>here are my imports:</p>
  
  <pre><code>import {Terrain} from 'react-icons/lib/md'
  import {SnowFlake} from 'react-icons/lib/ti'
  import {Calender} from 'react-icons/lib/fa'
  </code></pre>
  
  <p>Why am I getting this error?</p>
  
  <p>EDIT:</p>
  
  <p>i have also tried using the old syntax for importing, with the same issue as such:</p>
  
  <pre><code>import Calender from 'react-icons/lib/fa/calender'
  </code></pre>
