Issue #19271 has been updated by hsbt (Hiroshi SHIBATA). Status changed from Open to Assigned I couldn't reproduce this with fresh install of Ruby 3.2.0 from tarball. If you use `GEM_HOME` and share it with each Ruby versions or builds, you may encounter this (It's known issue). After I removed `GEM_HOME` environmental variable, I confirmed to work it correctly. ---------------------------------------- Bug #19271: irb ignores rbs and debug https://bugs.ruby-lang.org/issues/19271#change-101011 * Author: olivierlacan (Olivier Lacan) * Status: Assigned * Priority: Normal * Assignee: hsbt (Hiroshi SHIBATA) * ruby -v: ruby 3.2.0 (2022-12-25 revision a528908271) [arm64-darwin22] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Not sure this is a serious issue but when starting IRB this (potentially confusing) message is immediately printed: ``` $ irb Ignoring debug-1.7.1 because its extensions are not built. Try: gem pristine debug --version 1.7.1 Ignoring rbs-2.8.2 because its extensions are not built. Try: gem pristine rbs --version 2.8.2 irb(main):001:0> ``` This is on a fresh installation of Ruby 3.2.0 with an empty Gemfile in the directory. I haven't run gem pristine on any gem since I hadn't installed any gems after installing Ruby 3.2.0 here but FYI: ``` $ gem list | grep "rbs\|debug" debug (1.7.1) rbs (2.8.2) ``` This seems to suggest that C extensions weren't built for those gems when they were installed during the Ruby installation process. Just to be safe I checked and while I do use rbenv and ruby-build to compile and manage Rubies, I don't have a default gem installer set up so as far as I know these gems weren't installed by my system. -- https://bugs.ruby-lang.org/
