Remove explicit `psych` activation https://github.com/rubygems/rubygems/commit/1ccf0912a161d20e0c4a7b139fd76e8739a411ba bundler: Remove explicit `psych` activation. https://github.com/rubygems/rubygems/commit/88478bb56945ffa9868491cacd0bc74d9d73c848 It causes the following kind of error when psych is installed as not default gem but regular gem. It's a Fedora Ruby specific case. **This is not the case of Ruby built from source normally.** ``` $ cat test.rb require 'psych' Gem.load_yaml # <= The error happens. ``` ``` $ ruby test.rb /usr/lib64/gems/ruby/psych-3.1.0/psych.so: warning: already initialized constant Psych::Parser::ANY ... /usr/share/gems/gems/psych-3.1.0/lib/psych/parser.rb:34:in `': superclass mismatch for class Mark (TypeError) ``` It is possibly also related to https://github.com/ruby/psych/issues/386 .
