  <p>I tried to add factory_girl in Gemfile and execute <code>bundle install --path vendor/bundle</code></p>
  
  <p>I got another error :</p>
  
  <pre><code>Could not find gem 'factory_girl (~&gt; 2.0.1, runtime)' in any of the gem sources listed in your Gemfile.

  <p>Here is the <code>Gemfile</code>:</p>
  
  <pre><code>source "http://rubygems.org"
