Research direction

Start with the Ruby 2.4 failure in vendor/bundle/ruby/2.4.0/gems/test-unit-ruby-core-1.0.15/lib/core_assertions.rb and the require at test/lib/helper.rb:2. Check the CI run to identify how this dependency is selected. Done means the Ruby 2.4 CI job loads the tests without the reported SyntaxError.

Written by the indexing model from the issue text.

Description

The CI for Ruby 2.4 fails with a SyntaxError because the test library uses Ruby 2.5 syntax features.


Your RubyGems version (2.6.14.4) has a bug that prevents `required_ruby_version` from working for Bundler. Any scripts that use `gem install bundler` will break as soon as Bundler drops support for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning by running `gem update --system 3.2.3`
