title: How to install protractor and start it?
body: <p>I followed instructions in the document on how to install protractor and selenium and I am unable to start.</p>
  
  <pre><code>install -g protractor
  
  webdriver-manager update
  </code></pre>
  
  <p>After that I tried</p>
  
  <p><code>webdriver-manager start</code> and I got an error</p>
  
  <pre><code>events.jst:72
  throw er; // Unhandeled 'error event
  Error: spawn ENOENT
  at errnoException (child_projcess.js:980:11)
  at Process.ChildProcess.handle.onexeit (childprocess.js:771:34)
  </code></pre>
  
  <p>If I do <code>webdriver-manager status</code> I get this</p>
  
  <pre><code>selenium standalone is up to date
  chromedriver is up to date
  IEDriver is not present
  </code></pre>
  
  <p>What is going on?</p>
