问题 So we understand, I use Windows 7. I've been fighting my way through ruby.railstutorial.org/ruby-on-rails-tutorial-book, but I seemed to have split my command prompts. Originally, I installed Rails based on the instructions from here: http://railsinstaller.org/windows (this was where guides.rubyonrails sent here).
