HatchBox makes it incredibly simple to choose the Ruby version your app runs. All you have to do is set the version in .ruby-version or in your Gemfile
If you didn't specify either of those options, we'll default to using the latest version of Ruby.
Each time you deploy your app, we'll check your app's Ruby version and install the correct version.
This means you can easily upgrade to a new version of Ruby and we'll do all the heavy lifting for you.
All of this is powered by rbenv on your server. Don't worry though! If you use RVM, chruby, or any other Ruby version manager in development, they'll all be compatible with rbenv in production.
