Ruby Ruby Foundations Ruby Basics Installing Ruby

Does the Ruby version matters?

The version of Ruby 1.9.3 is installed as demonstrated in the video of Dive deep into Ruby tutorial. Now Ruby 2.0 is released and I noticed that an older version of Ruby 1.8.7 has been already installed in my Mac.

Does it matter if the new version 2.0 runs for this tutorial or just using the default version of Ruby installed by Apple?

Thanks.

Oh yes it can be very important. In particular if you are following a tutorial (like on Treehouse) then you can save yourself a world of pain by using the same version of Ruby and (most importantly) the same version of the Rails gem.

One important thing to understand is semantic versioning, there's a huge difference between the jump between 1.8.7 to 1.9.3 and 1.9.3 and 2.0.0.
