This article outlines how to define a specific version of Ruby for your application.
In your Gemfile
you can add the following line:
ruby '2.3.1'
You can find a full listing of Ruby version here. As a recommendation, we always suggest running the latest stable release of Ruby.
Once you've saved changes to your Gemfile, you can push your changes to Datica using git push datica master
. The platform will automatically detect the version change.
