setup-ruby's Introduction

setup-ruby

This action sets up a ruby environment for versions which are installed on the Actions Virtual Environments.

Virtual environments contain only one Ruby version within a 'major.minor' release, and are updated with new releases. Hence, a workflow should only be bound to minor versions.

Note that a ruby-version: of 2.6 or 2.6.x are equivalent.

Supports 2.4, 2.5, 2.6, and 2.7.
