title: Nokogiri error when running bundle install
body: <p>Trying to get a cloned Rails app running. When running <code>bundle install</code> I get this error:</p>
  
  <pre><code>Using mini_portile (0.5.0)
  Installing nokogiri (1.6.0)
  Gem::InstallError: nokogiri requires Ruby version &gt;= 1.9.2.
  An error occurred while installing nokogiri (1.6.0), and Bundler cannot continue.
  Make sure that `gem install nokogiri -v '1.6.0'` succeeds before bundling.
  </code></pre>
  
  <p>But this is the output for <code>rbenv version</code>:</p>
  
  <pre><code>› rbenv version

  <p>Here's a more verbose error output: </p>
