I am learning how to build web application on ruby with rails gem. Following this tutorial: http://12devs.co.uk/articles/writing-a-web-application-with-ruby-on-rails/
All was good & clear before I started to install Devise gem for user authentication feature.
I am getting error after doing rails generate devise:install
Error report is this epic (looks like I messed up some dependencies somehow):

I know there is a question with same error here (even with similar versions) devise gem install for Ruby on Rails
But unanswered and I tried to provide more info.
Also I tried this answer, no effect.
Could you please help me out here?
