Use multiple versions of rubygems with rvm?

I have two projects on my computer: - An old Rails 2.3 app that needs rubygems 1.6 and won\'t run under rubygems 1.8; - A newer app that needs rubygems 1.8 and won\'t run under

Answer 1

RVM has a new feature for this:

use "rvm rubygems 1.6.2" to select that version of rubygems.

 rvm rubygems 1.6.2
