Is it possible to run Ruby on Rails with Ruby 1.9x?

Question

If so, how?

When you go to http://rubyonrails.org/download , he says:

We recommend Ruby 1.8.7 for use with Rails. Ruby 1.8.6, 1.8.5, 1.8.4, and 1.8.2 are still usable, but version 1.8.3 is not.

Answer 1

Rails works from 1.9 to 2.3. I believe that they still recommend Ruby 1.8.7 because it has great compatibility with other Ruby libraries - many of them are still catching up.

Answer 2

From the Rails 2.2 ad announcement :

Ruby 1.9 JRuby. Rails 2.2 , , , . , , .

Rails 2.3:

Rails 2.3 , , Ruby 1.8 Ruby 1.9.1. , 1.9.1 , , Ruby 1.9.1, Rails.

Answer 3

, Rails 2.3.0RC1 Ruby 1.9.1 (, , 1.9 ). , .

Answer 4

Rspec has only recently been ported to 1.9, so many gems have not been able to launch their test packages in 1.9 until recently, so many gems are not yet stable in 1.9
