title: Unable to find the chromedriver executable... seems like it's in my path?
body: <p>I'm using Ubuntu 13.10 64bit with Watir and Ruby.</p>
  
  <pre><code>browser = Watir::Browser.new :chrome
  </code></pre>
  
  <p>Gives an error: "Unable to find the chromedriver executable. Please download the server from"...</p>
  
  <p>I've downloaded and extracted the file (I've tried both 64 bit and 32 bit) into /usr/bin/ but I still get the error.</p>
  
  <pre><code>/usr/bin$ la | grep chrome
  chromedriver
  google-chrome
  </code></pre>
  
  <p>Here is my $PATH:</p>
  
  <pre><code>/usr/bin$ $PATH
  bash:    /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/dan/.rvm/bin: No such file or directory
  </code></pre>
  
  <p>It looks ok to me, what am I missing?</p>
