I know this is documented on the official RVM website, but I hate having to look it up over and over again each time I want to create a new RVMRC file.

I’m needing to setup a Rails 2.3.8 system, so I can test my gem for compatibility between it and Rails 3.0.9.
I stumbled onto an article with suggestions for how to install RubyGems for Rails 2.3.8. This seems to run with errors, but the last command seemed to complete without errors other than ‘README’ not found:
$ rvm all do gem install -v 1.4.2 rubygems-update $ rvm gem update --system 1.4.2 $ update_rubygems $ rvm all do gem install -v 2.3.8 rails $ rails --version Rails 2.3.8 $ ruby --version ruby 1.8.7 (2012-02-08 patchlevel 358) [i686-darwin10.8.0]
