Can I play with Rails 3 without destroying my Rails 2 setup?


I should start playing with Rails 3 but I don’t want to use a different
machine for that.

I am currently on Rails 2.3.5 and I’m not yet using RVM.
I know the RVM will help on the Ruby side. But what about the Rails
side, how can I make sure I can start Rails 3 but use Rails 2 for
“normal” work?
I’m on OSX.

You want RVM. You can change not only your Ruby but also your GEMHOME.
That means you can install Rails 3 in one install and never allow its
gems to touch your Rails2 install. I installed REE and Rails3 for one
installation and 1.8.7 and Rails 2 for another. Works great.

Thanks Steve!
