title: Is Nokogiri necessary for Rails?
body: <p>I updated my Ruby from 1.9 to 2.2 and I found that the Nokogiri gem doesn't support Ruby 2.2 on Windows. Nokogiri was not in my Gemfile, but when I run <code>bundle install</code> it is automatically added. Maybe there are some dependency for it? </p>
  
  <p>This is a very small project and I don't understand its necessity for the project.</p>
  
  <p>Is it possible to use Ruby 2.2 without Nokogiri? Or should I downgrade to 1.9 again?</p>
