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.
This works!
This means to set the "system" ruby as default, you reset RVM's defaults as follows.
rvm reset
NOTE: it works only when there is no default ruby set:
rvm alias delete default
