- JRuby (currently supporting version 1.7.x)
Recommended: Use RVM to install and manage all Ruby (and JRuby) versions on your machine.
Because Pacer runs on top of JRuby, it runs on any operating system that can run JRuby - Linux, Windows and OS X.

If you already have RVM installed, you may want to update it to the latest version:
Note: After the installation completes, you will need to
source ~/.rvm/scripts/rvm before you can use RVM from your console.
Use RVM to install JRuby:
Switch RVM to use JRuby (optionally setting it to be default):
$ rvm use --default jruby
We can verify that Pacer was properly installed, using the IRB (Ruby's interactive shell):
jruby-1.7.19 :001 > require 'pacer'
That's it, you're good to go.
Tip: Windows users may find it more convenient to use
jirb_swing, instead of running IRB in the built-in CMD terminal.
