Getting Started with JRuby
JRuby is one of the easiest Ruby implementations to set up. Let’s start with the basic instructions:
- Download JRuby: Visit the download page and grab the binaries for the latest JRuby release.
- Unpack JRuby: Unpack the file you downloaded. You’ll then have a "jruby-<version>" directory.
- Run JRuby: The JRuby startup script lives in the "bin" directory. Run "bin/jruby -v" to confirm it.
That’s about it!
If you’re on Windows, we’ve already prepared several flavors of installers for you. Just pick 32- or 64-bit, and whether to bundle the Java Virtual Machine or not.
Other ways to get JRuby
If you use RVM, then installing JRuby is also a piece of cake:
rvm install jruby
JRuby might also be available as OS packages for your favorite package manager, check the JRuby Distributions page for more information.
