I\'m new to Ruby and Rails and I installed the latest beta version of Rails 4 on my Mac, before I installed RVM to manage my versions. The Rails 4 beta is becoming a huge pain i
and choose the version 4 beta as the one to uninstall. Do not worry about unmatched dependencies at this point. Just say 'yes' to go ahead with the uninstall.
Once it is gone, do
$ gem install rails
This will get and install the latest released version for you.
