body: <p>I am trying to get Protractor up and running following the official <a href="https://github.com/angular/protractor/blob/master/docs/getting-started.md" rel="noreferrer">Getting Started Guide</a>.</p>
  
  <p>The command</p>
  
  <pre><code>webdriver-manager start
  </code></pre>
  
  <p>seems to run smoothly:</p>
  
  <pre><code>webdriver-manager start
