It might be throwing this error because of Chrome update where as webdriver is not supporting the updated API's,
I also tried to update watir-webdriver gem, but it is saying nothing to update (its up to date) My watir-webdriver version is watir-webdriver-0.6.4
Kindly let me know if any one else is facing the same issue or any one found out the solution for the same.
Download the latest version of chromedriver. Also make sure that the old old on NOT in your PATH.
