title: Sinatra error: "Gem::LoadError: Unable to activate actionpack-3.2.3, because activesupport-3.2.8 conflicts with activesupport (= 3.2.3) "
body: <p>I would like to comma delimit large numbers in my Sinatra app, so I did some Googling and found that I can do so by adding the following:</p>
  
  <pre><code>require 'action_view/helpers/number_helper'
  </code></pre>
  
  <p>Then, it seems I am supposed to be able to do things like: </p>
  
  <pre><code>number_with_delimiter(12345678, :delimiter =&gt; ',')
  </code></pre>
  
  <p>However, I get the following error: </p>
  
  <pre><code>Gem::LoadError: Unable to activate actionpack-3.2.3, because activesupport-3.2.8 conflicts with activesupport (= 3.2.3)
  </code></pre>
  
  <p>I'm not sure how to fix this. </p>
