Easily switch between Ruby 1.8.6 and 1.9.1
NOTE: I don't keep Ruby Switcher updated anymore. Use RVM instead.
Chad mentioned that he'd gotten ruby 1.9.1 and 1.8.6 side by side on his workstation (his code for this is in his awesome spicy-config repo).
I took some time this morning to get a similar setup working. Now, on my prompt, I type, use_ruby_186 or use_ruby_191 to go back and forth between the Ruby 1.8.6 shipped with Leopard and a self-compiled install of ruby 1.9.1.
Steps for you to get there:
- Compile and install ruby 1.9.1:
mkdir -p ~/tmp cd ~/tmp curl -O ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p0.tar.gz tar xzf ruby-1.9.1-p0.tar.gz cd ruby-1.9.1-p0 ./configure --prefix=$HOME/.ruby_versions/ruby_191 make make install
- Install the ruby switcher:
curl -L http://github.com/relevance/etc/tree/master%2Fbash%2Fruby_switcher.sh?raw=true?raw=true > ~/ruby_switcher.sh echo "source ~/ruby_switcher.sh" >> ~/.bash_profile
Note that I use ~/.gem for my gems. If you don't do that, you'll have to modify the switcher to specify your GEM_HOME. Type gem env and look for GEM PATHS to figure out what you should set it to.

I just install both side by side: http://tr.im/gFJN?github
I created a dedicated repo for the ruby_switcher.

Are there any guarantees with the switching shell that other gems and other stuff won't be messed up? I just spent two hours trying random google results to get RSRuby to work in Ruby 1.8 (Ubuntu 10.04).
human mathematics: the script switches Gem directories. However, I suggest you use RVM instead. It's more complicated, but what the community has settled on for installing and switching between multiple rubies.
