title: Ruby Gem - LoadError
body: <p>Ruby newbie here trying to figure out how to use a Gem and thus far the experience is not that great.</p>
  
  <p>After installing mysql2 via gem I tried to use it in a simple file.</p>
  
  <pre>
  require 'mysql2'
  
  #client = Mysql2::Client.new(:host => "localhost", :username => "username")
  </pre>
  
  <p>Though when I run this I get:</p>
  
  <pre>
  
  Parse.rb:1:in `require': no such file to load -- mysql2 (LoadError)
   from Parse.rb:1
  </pre>
  
  <p>Yet my gem list contains mysql2:</p>
