Ruby Versions

How do I specify my app's Ruby version?

You have two options:
    Write your Ruby version to a file called .ruby-version in the root of your git repo
      echo "2.6.3 > .ruby-version"
      git add .ruby-version
      git commit -m "Set ruby version"
    Or you can manage it in your Gemfile
      ruby "2.6.3"
      bundle
      git add Gemfile Gemfile.lock
      git commit -m "Set ruby version"
For legacy versions of Ruby, we only support the latest patch versions.
