I just downloaded Ruby 1.9.2, and I want it to completely replace the older version of Ruby (1.8.7) that I also have installed. (Mostly because I get confused when installing things with different versions floating around.)
What’s the best way to do this? Do I uninstall the older version? (If so, how?) Can I just replace the old ruby1.8.7/bin/{ruby,irb} with the new ruby1.9.2/bin/{ruby,irb}?
I’m on a Windows 7 machine.
This isn’t the answer you’re looking for, but hopefully will help you in the future. You can use Pik on Windows (as opposed to RVM on Linux/Mac) to manage multiple concurrent versions of Ruby on the same development environment.
