body: <p>I'd like to generate some devise views for an application, but whenever I try to use the command <code>rails g devise:views</code>, I get a complex error, well above my understanding. </p>

  <p>One of these lines, <code>/Users/michaeldunnegan/projects/SoundShare/config/environment.rb:4:in</code>'`</p>
  
  <p>is interesting. All I have in that file is:</p>
  
  <pre><code># Load the Rails application.
  require File.expand_path('../application', __FILE__)
  
  SoundShare::Application.initialize! # this is the line
  </code></pre>
