Overview

Read Ruby version from a .ruby-version file

Instead of staticly defining the Ruby runtime version in Gemfile, load it from a .ruby-version file definition. As this Ruby version file is read by rbenv, chruby etc it’s much easier for the developer to work with multiple projects with different versions.

Examples:

# bad
ruby 2.6.6

# good
ruby File.read('.ruby-version')

Constant Summary collapse

MSG = 
"Control Ruby version via .ruby-version, fix by replacing with File.read('.ruby-version')"
