[ruby-core:111644] [Ruby master Bug#19158] Ruby 3.1.3 installs wrong gemspec for debug gem

Issue #19158 has been updated by hsbt (Hiroshi SHIBATA).





@deivid @nagachika did backport the installer toolchain like `rbinstall.rb`=
 into `ruby_3_1` branch for releasing Ruby 3.1.3. Maybe, this issue contain=
ed its time.



----------------------------------------

Bug #19158: Ruby 3.1.3 installs wrong gemspec for debug gem

https://bugs.ruby-lang.org/issues/19158#change-101026



* Author: deivid (David Rodr=EDguez)

* Status: Assigned

* Priority: Normal

* Assignee: nagachika (Tomoyuki Chikanaga)

* ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [arm64-darwin22]

* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: REQUIRED

----------------------------------------

A pristine installation of Ruby 3.1.3 shows an installed `debug-1.6.3.gemsp=
ec` file that claims that debug-1.6.3 has no dependencies. This is incorrec=
t, 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 debu=
g:1.6.3`. That will reinstall the gem, including a correct gemspec file.



This is the file diff before and after reinstalling the gem

In general, the files installed by ruby-core for bundled gems should be ide=
ntical to the ones installed by explicit `gem install`.



This issue is also present in master and I'm guessing it was introduced by =
