title: uninitialized constant Request (NameError)
body: <p>I get this error: <code>/LiveToChallenge/config/initializers/gibbon.rb:1:in '&lt;top (required)&gt;': uninitialized constant Gibbon::Request (NameError)</code> when I try to start the server <code>rails server</code>.</p>
  
  <p><strong>app/config/initializers/gibbon.rb</strong></p>
  
  <pre><code>require 'gibbon'
  Gibbon::Request.api_key = "24e4a2233cd34debb76ed083dc3f8b5379-us8"
  Gibbon::Request.timeout = 15
  </code></pre>
  
  <p>I followed <a href="https://github.com/amro/gibbon" rel="nofollow noreferrer">gibbon gem</a> instructions, which seemed simple enough. Maybe I'm missing something besides just <code>gem install gibbon</code> and adding <code>api_key</code> to initializer?</p>
  
  <p>The gem is installed as <code>gibbon (2.2.2, 2.2.1, 1.2.1)</code></p>
  
  <p>And as added measure I put <code>gem gibbon</code> in the gemfile and ran <code>bundle install</code></p>
  
  <p>This problem is part of a <a href="https://stackoverflow.com/questions/35949045/how-to-save-email-to-subscribers-with-checkbox">larger problem</a> I've been working on solving.</p>
