title: Protractor ERROR - Unable to start a WebDriver session
body: <p>I'm trying to run the plain vanilla Protractor example at <a href="http://angular.github.io/protractor/#/" rel="nofollow noreferrer">http://angular.github.io/protractor/#/</a>.  I've done all the steps, but I get the errors below.</p>
  
  <p>I have tried the solutions <a href="https://stackoverflow.com/questions/28010502/protractor-error-unable-to-start-a-webdriver-session">HERE</a> and <a href="https://stackoverflow.com/questions/27493715/protractor-gives-unable-to-start-a-webdriver-session-error">HERE</a>  with <code>binary: "/Applications/Google\ Chrome.app"</code> and <code>binary: "/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome"</code>, and neither works</p>
  
  <p>I'm not really sure what else I can configure; it just doesn't seem to work.  Any idea as to what I can do to get it working?</p>
  
  <p><strong>EDIT</strong>
  I can see the status at <a href="http://localhost:4444/wd/hub" rel="nofollow noreferrer">http://localhost:4444/wd/hub</a>, so not sure if the problem is with protractor config or with webdriver-manager.</p>
  
  <p><strong>Error in webdriver-manager:</strong></p>
