title: Unable to start Rails server nor console - (crack/xml) LoadError
body: <p>I've searched all around the web but haven't been able to find a resolution to this error. Each time I attempt to either start the rails server, or even rails console I get a <code>crack/xml (LoadError)</code>. Anyone have any suggestions that they believe might help me get rails up and running correctly?</p>

  <p>I've attempted to install the crack gem then run bundler but I'm still given the same error, even after a reboot of terminal. So I'm not exactly sure how to solve this scenario.</p>
