For rails application I had installed Ruby 1.8.7 and Rails 2.3.11. And it was working fine. After that I have installed RVM and REE. So while running ruby script/server it's using REE. But now I want to use the older Ruby 1.8.7 which was installed without RVM.
Any Solution!
Try rvm use system
to use the system ruby which is not managed via. rvm.
