I’m using different books to learn rails and they’re all using different versions of ruby and rails. I’ve got instructions on how to load/use different versions of rails, but I don’t know how to do it with ruby.
Can anyone tell me if this is possible and how to indicate which ruby I am using for each app?
i’m using mac os snow leopard. ruby 1.87 is installed currently in usr/bin
Use rvm. It manages different ruby versions and even different gemsets (e.g. per application).
