Answer 1

Well, the error message says it all. You have to install chromedriver:

Answer 2

You have to install/configure ChromeDriver. The following are the steps:

1. Download chromedriver if you want to use google chrome for testing (recommended) from: http://chromedriver.storage.googleapis.com/index.html (I downloaded 2.13 version for Windows7)
2. Place in your PATH as follow:
   Ubuntu: usr/bin
   Windows: The ruby install folder is a good place, (usually C:/ruby###)/bin

Answer 3

On Mac, I found that not all PATH directories worked. Pasting the file in this path (folder), however, did work for me (make sure its called 'chromedriver', not 'chromedriver2'! (happened b/c of duplicate download)

/Users/[mac_account_name]/.rvm/gems/ruby-1.9.3-p286/bin/

Obviously, I use rvm.

(be sure to restart the shell after you add it to pick up the changes)
