title: Gem dependency conflict
body: <p>I have run into a similar issue as a previous question, that was posted over a year ago.
  <a href="https://stackoverflow.com/questions/6559863/how-do-i-fix-this-gem-dependency-problem-in-rails-3-bundler">How do I fix this gem dependency problem in Rails 3 (bundler)?</a></p>
  
  <p>I am new to ROR. When trying to run <code>bundle install</code> on an application, i receive the following:</p>
  
  <p><code>Could not find twitter-2.5.0 in any of the sources</code></p>
  
  <p>I tried to delet my Gemfile.lock. And tried <code>bundle install</code> again. And received the output:</p>
  
  <pre><code>Bundler could not find compatible versions for gem "faraday":
    In Gemfile:
      twitter (&gt;= 0) ruby depends on
        faraday (~&gt; 0.8) ruby
  
      omniauth (~&gt; 0.3.2) ruby depends on
        faraday (0.7.3)

  <p>I also tried the suggestions of adding <code>gem 'twitter', :git =&gt; 'https://github.com/sferik/twitter.git'</code> to my gemfile but also had no luck.</p>
  
  <p>Any help would be appreciated. Thanks.</p>
