Yeah I still don't have it installed correctly. I've been trying any way I know how to complete the installation on my drive on the university's Linux servers. I can get RVM, and Ruby 2.1.0 installed but after that it's just a nightmare. The directions tell me I need to run "bundle install" which requires a file by the name of "Gemfile." Problem is I have about 4 of these Gemfiles which supposedly after installing, allows the Ruby installation to use Rails 3 & 4. However none of them install correctly, and don't allow Ruby 2.1.0 to access Rails. It just spits out some HTML gibberish and returns.
I got so frustrated with it earlier I had to take off and go for a drive. Lol.
That's my biggest problem with RoR. It's such a beast to install, but once you get it running the development process can go quite fast.
