title: Gem::LoadError: Rake?
body: <p>I'm trying to run <code>rake db:migrate</code> locally but I'm getting the below error:</p>
  
  <pre><code>Gem::LoadError: You have already activated rake 10.2.2, but your Gemfile requires rake 10.1.1. Using bundle exec may solve this.
  </code></pre>
  
  <p>Not sure why this is happening? It came out of no where.</p>
  
  <p>Any idea how to resolve this? </p>
  
  <p>Cheers</p>
