How to update ruby on linux (ubuntu)?

Question

I\'m newbie on both ruby and linux, so I\'m sure this is trivial but I don\'t know yet. I currently have ruby 1.8.7 installed and I want to update it to ruby 1.9. How can I do t

Answer 1

There's really no reason to remove ruby1-8, unless someone else knows better. Execute the commands below to install 1.9 and then link ruby to point to the new version.

sudo apt-get install ruby1-9 rubygems1-9
sudo ln -sf /usr/bin/ruby1-9 /usr/bin/ruby
