title: Rails route error? uninitialized constant ActiveResource::Base
body: <p>I'm following the <a href="http://guides.rails.info/getting_started.html#say-hello-rails" rel="nofollow noreferrer">Getting Started with Rails</a> guide but ran into an issue opening <a href="http://localhost:3000" rel="nofollow noreferrer">http://localhost:3000</a></p>
  
  <p>Shell output:</p>
  
  <pre><code>[2010-03-23 19:19:14] ERROR NameError: uninitialized constant ActiveResource::Base
  </code></pre>
  
  <p>Error in the browser:</p>
  
  <pre><code>Internal Server Error
  uninitialized constant ActiveResource::Base
  WEBrick/1.3.1 (Ruby/1.8.7/2009-06-12) at localhost:3000 
  </code></pre>
  
  <p>I followed the directions exactly as they were specified in the guide:</p>
  
  <ol>
  <li>Ran <strong>rails generate controller home index</strong></li>
  <li>I removed index.html</li>
  <li>Added <strong>root :to => "home#index"</strong> to <em>config/routes.rb</em> </li>
  </ol>
  
  <p>I checked app/views/home/index.html.erb and it is indeed there.</p>
  
  <p>I then used <strong>rails server</strong> to launch the server. At first attempt the browser loads a blank page, but afterwards starts showing the browser error above.</p>
  
  <p>Why is it that Rails can't locate the index.html.erb file? Or is the error something different?</p>
