Answer 1

This normally occurs when you have multiple versions of RVM and gem sets and its normally comes for ruby 2.2.2 the best way to get rid of this ERROR is.

First Update your system gems by using the following

 gem update --system   

 OR  

 update_rubygems --system

Then you have to update your bundler:

 gem update bundler
