Issue #19158 has been reported by deivid (David Rodríguez). ---------------------------------------- Bug #19158: Ruby 3.1.3 installs wrong gemspec for debug gem https://bugs.ruby-lang.org/issues/19158 * Author: deivid (David Rodríguez) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [arm64-darwin22] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- A pristine installation of Ruby 3.1.3 shows an installed `debug-1.6.3.gemspec` file that claims that debug-1.6.3 has no dependencies. This is incorrect, and causes issues for Bundler as reported at https://github.com/rubygems/rubygems/issues/6082. An issue workaround is to manually reinstall the gem with `gem install debug:1.6.3`. That will reinstall the gem, including a correct gemspec file. This is the file diff before and after reinstalling the gem ```diff --- old.gemspec 2022-11-29 13:54:36 +++ /Users/deivid/.asdf/installs/ruby/3.1.3/lib/ruby/gems/3.1.0/specifications/debug-1.6.3.gemspec 2022-11-29 13:55:25 @@ -24,4 +24,16 @@ s.summary = "Debugging functionality for Ruby".freeze s.installed_by_version = "3.3.26" if s.respond_to? :installed_by_version + + if s.respond_to? :specification_version then + s.specification_version = 4 + end + + if s.respond_to? :add_runtime_dependency then + s.add_runtime_dependency(%q<irb>.freeze, [">= 1.3.6"]) + s.add_runtime_dependency(%q<reline>.freeze, [">= 0.3.1"]) + else + s.add_dependency(%q<irb>.freeze, [">= 1.3.6"]) + s.add_dependency(%q<reline>.freeze, [">= 0.3.1"]) + end end ``` In general, the files installed by ruby-core for bundled gems should be identical to the ones installed by explicit `gem install`. This issue is also present in master and I'm guessing it was introduced by https://github.com/ruby/ruby/commit/a2c66f52f402cb58372e271226f3341065561e53 (backported at https://github.com/ruby/ruby/commit/2d26e45135af8b427d9ccc6d47082c21be8b9c74). -- https://bugs.ruby-lang.org/
