Rails 4

Can Ruby 2.0 and Ruby 1.9.x coexist on my computer. I want to have both and be able to switch back and forth between Rails 3 & 4 projects also.

I know I can specify which version of Ruby and Rails in my gem file of 3 right now but Im not sure that is the solution because I think Rails generates slightly different files in 3 & 4.

Would there be a way to specify version before I generate a project?

  • I havent downloaded Ruby 2.0 or Rails 4 yet but I will once I hear about someone else that safely has both.

rbenv to the rescue!

rbenv

This will allow you to set local and global versions of ruby. It also allows for a .ruby-version file per application which will switch the version or prompt you to install the correct version of ruby per the applications requirement.

Some will recommend: rvm

But I have run into various issues over time with rvm and rbenv has been a breeze.
