How do I make Ruby 1.9 the default Ruby on Ubuntu?

Question

Is there any way, on Ubuntu 9.04, to install Ruby 1.8 as ruby1.8 (or get rid of it altogether) and have Ruby 1.9 be the default ruby?

Answer 1

Try this:

sudo apt-get install ruby1.9.1 rubygems1.9.1

or try building from source. this worked for me on ubuntu 9.04 and after a restart 1.9 was the standard ruby
