Can't run server rails in Treehouse workspace

I had some issues getting rails up and running on my own environment, so I thought I would try doing the course in a Treehouse workspace with the Ruby environment for now. I'm running into an issue where it gets stuck on this 'nokigiri' gem and then eventually times out. I've tried a few times. From my command line:

treehouse:~/workspace$ ls                                                                                                      
treehouse:~/workspace$ cd blog                                                                                                 
treehouse:~/workspace/blog$ ls

I'm afraid Rails just doesn't work in Workspaces. We attempted to create a setup where Rails was pre-installed for students (Nokogiri and all), but it turns out that Workspaces filesystem access is too slow to run an app reliably (if at all).

You might have better luck installing Linux on VirtualBox and then installing Rails within Linux.
