Should I use Ruby 1.9x or 2.0x?

ruby, ruby-1.9.3, ruby-2.0, ruby-on-rails-4

Solution

You should use ruby 2.1.1. The difference between Python 2 and 3 is so great that there are major backward compatibility issues. As this is not the case with ruby 1.9 vs 2.X you better start with the most current technology.

Problem

I used to write some Python, and I know there are a lot of difference between Python 2.x and Python 3.x Current now, I hope to use some Ruby to write a website (Maybe use Rails), but I am afraid that there will be the same problem in Ruby like Python. Since I am a newcomer to Ruby, I just wonder what should I learn Ruby 1.x or Ruby 2.x?
