title: Guard-rails not providing REPL for binding.pry
body: <p>I'm using guard-rails to run my rails server, my problem is I can't access the REPL when I add binding.pry I just get</p>
  
  <pre><code>From: /home/martinr/code/app/controllers/tools_controller.rb @ line 2 ToolsController#index:
  
      2: def index
   =&gt; 3:   binding.pry
      4:   @end_date = Date.today.to_s
      5:   @start_date = Date.today.months_ago(3).to_s
      7: end
  
  [1] pry(#&lt;ToolsController&gt;)&gt; 
  </code></pre>
  
  <p>No REPL, how do I use pry with guard rails?</p>
  
  <p>My Gemfile file looks like this</p>
  
  <pre><code>group :development, :test do
    gem 'pry-rails' # for better console debugging
    gem 'pry-debugger'
    gem 'rb-inotify'
    gem 'sqlite3'
  end
  </code></pre>
  
  <p>My Guardfile:</p>
  
  <pre><code>guard 'rails', :debugger =&gt; true do
    watch('Gemfile.lock')
    watch(%r{^(config|lib)/.*})
  end
  </code></pre>
