Proof Of Concept - 6 of 8 : Install JRuby

Go to JRuby home page and download the zip file. As of this writing, the current version is 1.1.6.

1. I extracted the zip file into C:\jruby\jruby-1.1.6RC1
2. Added the above path on to the end of PATH environment variable
3. Add new environment variable JAVA_HOME with value C:\Program Files\Java\jdk1.5.0_17 (this directory was created with installation of Java SDK in Proof Of Concept 3 of 8)
4. To test whether it installed correctly, run:

   
   jruby -v 
   

   
   

The above command will return the current version.
