title: Selenium::WebDriver::Error::WebDriverError:
body: <p>I am trying to run some acceptance tests for javascript code. However, when I tried using Capybara with Selenium, I kept getting the following:</p>
  
  <pre><code>&gt;&gt; Thin web server (v1.3.1 codename Triple Espresso)
  &gt;&gt; Maximum connections set to 1024
  &gt;&gt; Listening on 0.0.0.0:1234, CTRL+C to stop

         Unable to find the chromedriver executable. Please download the server from http://code.google.com/p/chromedriver/downloads/list and place it somewhere on your PATH. More info at http://code.google.com/p/selenium/wiki/ChromeDriver.&gt;&gt; Thin web server (v1.3.1 codename Triple Espresso)

  <p>The code below is what is supposed to start the driver. I downloaded the appropriate file from <a href="http://code.google.com/p/chromedriver/downloads/list" rel="nofollow">http://code.google.com/p/chromedriver/downloads/list</a> and I placed it in my Path by running PATH=$PATH:/directory/where/chromedriver/exists and export PATH, and made it executable but still got the error. Is there something I am missing?</p>
