Install macports. Then: sudo port install ruby19 Should do it. Ben ---

Great. You’ll find macports pretty handy for installing many things. ---

One thing I’m noticing is when I type /usr/bin/ruby -v it is giving me version 1.8, when I’m compiling my code how do I know which version of ruby I’m using? 1.9 is installed in my /opt/local/lib directory. Should I uninstall 1.8? Thanks ---

Although, in fairness this seems to work quite well for java on the mac. Anyway, check your path with either echo $PATH of env commands and see what it says. You may have to force it by modifying the path in .bash\_profile in your home directory (assuming bash) or some other file that’s modifying your path variable. Hope that helps. ---

Take a look at this article: [http://www.metaskills.net/2009/1/20/multiruby-the-macports-way-testing-your-rails-apps-with-ruby-1-9](http://www.metaskills.net/2009/1/20/multiruby-the-macports-way-testing-your-rails-apps-with-ruby-1-9) Although it is a little hackish I’m not sure of any easier method.

Sorry but I cannot find the file to modify my path env variable. Thanks ---

I always install alternative versions of any software into different directories, e.g. /usr/local/ruby-1.8.6 /usr/local/ruby-1.8.7 /usr/local/ruby-1.9.1 ## set the default path in your .bashrc.local or equiv, and then use a file like, say “r187” ## export RUBY\_HOME=/usr/local/ruby-1.8.7 export PATH=$RUBY\_HOME/bin:$PATH for each version. Then in any window you can type prompt\> . r187 and set the version for that particular shell. FWIW,
