JRuby and RVM, Revisited
In an earlier post I wrote about installing JRuby via RVM. In a footnote, I mentioned
JRuby 1.6.0, which should be out Any Day Now, is supposed to be fully compatible with Ruby 1.9.2.
Well, kids, that day is today. 1
First update RVM to version 1.2.9 or higher.
Then install JRuby 1.6.0.
RVM won’t remove any older version of JRuby you may have installed, so you have both available to do comparisons if you like. At the very least, you probably should copy over the installed gems so your JRuby 1.6.0 environment will behave as much like your older environment as possible.
Now, let’s check it out.
Interesting – JRuby 1.6.0 is still supporting Ruby 1.8.7 out of the box. Enabling 1.9 support is the same as before.
Once you’re confident the new JRuby is working correctly, it’s easy to remove the old one.
Actually, two days ago. That’s not important right now. ↩
