People want to start working on apps in Rails 3.0. Rails 3 is supporting ruby 1.8.7 and ruby 1.9.2. These instructions will assist you with getting Rails 3 and ruby 1.9.2 installed. I’m tossing this up here to have something to point people to when they have questions.
I’m making a few assumptions:
You’re on OS X Snow Leopard (x86_64) (Most of these instructions will work on any *nix box. Leave a comment if you have trouble.)
You have macports install (or readline installed somewhere else on your box)
##Install Ruby Version Manager
Note: Just run this command and follow the instructions.
##Install Ruby 1.9.2
Your readline directory may be in a different spot.
##Create a Rails 3.0 Gem set and switch to it
This processes allows us to isolate the Rails 3.0 environment gems.
##Install the Rails 3.0 Gems and dependencies
Hopefully everything worked:
##Switching back to your system Ruby
##Back to your Rails3.0 environment
##Use your RVM environment as your Default
rvm 1.9.2@rails3 --default
