title: RubyInstaller 2.2.1 and Rails - Rake cannot load Nokogiri
body: <p>recently I installed Ruby 2.2.1 with the new RubyInstaller on Windows. To check whether everything was working I went into a rails app and ran <code>bundle install</code> which was working fine. However, when I ran the tests with <code>bunle exec rake test</code>, I got the following errors:</p>
  
  <pre><code>rake aborted!
  LoadError: cannot load such file -- nokogiri/nokogiri
  D:/Dev/Grummle/config/application.rb:7:in `&lt;top (required)&gt;'
  D:/Dev/Grummle/Rakefile:4:in `&lt;top (required)&gt;'
  LoadError: cannot load such file -- nokogiri/2.2/nokogiri
  D:/Dev/Grummle/config/application.rb:7:in `&lt;top (required)&gt;'
  D:/Dev/Grummle/Rakefile:4:in `&lt;top (required)&gt;'
  (See full trace by running task with --trace)
  </code></pre>
  
  <p>Bundler says that it is <code>Using nokogiri 1.6.5</code>. Also, the rake task is working fine with Ruby 2.1.5. I appreciate ideas on how to resolve the issue. Thanks! :)</p>
