title: Ruby on Rails - $ rails server fails because uglifier gem could not be found
body: <p>I'm starting my first project on Ruby and the tutorial I'm following has me using rails.  When I try to run <code>$ rails server</code> I get an error that says: Could not find gem <code>uglifier (&gt;=1.3.0) x86-mingw32</code> in the gems available on this machine.  </p>
  
  <p>I had this error with a few other gems, and I was able to fix it by simply doing the <code>gem install</code> of the gem at hand, but this one is giving me errors.  These errors started to appear after I tried to install the dev kit for the first time.  When I try <code>$ gem install uglifier</code> I get a large mess of errors that can be seen <a href="http://i.imgur.com/CyqJIlp.png" rel="nofollow">here</a>.  </p>
  
  <p>I am running on a Windows 8 tablet.  While I realize Ubuntu is the preference for this situation, I'm trying to make the best with what I'm given.  Any help would be greatly appreciated.</p>
