Answer 1

Rvm exists for this very reason - you don't need to remove ruby 1.9.2 to add 1.8.7. Check out the rvm cheat sheet and look under the "Install Ruby" and "Selecting Ruby for Work" headings.

Namely, you should be able to run rvm install 1.8.7 then rvm use 1.8.7 when you want to switch to it. Just run rvm use 1.9.2 when you want to switch back to Ruby 1.9.2.

Answer 2

Have you tried:?

apt-get install ruby1.8

And then tried running:

$ ruby1.8
