I installed Ruby on Rails on my PowerMac G5 a few months ago and was wondering how to check which version is running? If it's not current, can someone tell me how to upgrade or point me to a site that explains this?
There are a few ways, from a terminal you could type "gem list". Or you could create a Rails project, and then look at environment.rb.
Type in terminal:
gem update rails --include-dependencies
yes | gem update rails
in terminal to update.
