Anyone know why Apple didn't update Ruby to 1.9.2 in Lion?


Most likely they were worried about breaking existing scripts since 1.8 has been the official Ruby of Mac OS X for pretty much its entire lifetime. Ruby 1.9 is better, but it did manage to break a decent number of programs.


If you need 1.9.2, the cleanest way to currently get it is via RVM.

Install RVM, then:

  rvm install 1.9.2
  rvm --default use 1.9.2
