Issue #19985 has been updated by usa (Usaku NAKAMURA). note: also needs backporting b5c74d54887 ---------------------------------------- Bug #19985: Confusing error message when nonexistent `Pathname` for `require` https://bugs.ruby-lang.org/issues/19985#change-105203 * Author: vo.x (Vit Ondruch) * Status: Closed * Priority: Normal * Backport: 3.0: REQUIRED, 3.1: DONE, 3.2: REQUIRED ---------------------------------------- It seems that RubyGems / Bundler `require` method overrides of accept `Pathname` as and argument ~~~ $ ruby -rpathname -e ' pa = Pathname.new("test") require pa ' <internal:/usr/share/rubygems/rubygems/core_ext/kernel_require.rb>:85:in `require': cannot load such file -- test (LoadError) from <internal:/usr/share/rubygems/rubygems/core_ext/kernel_require.rb>:85:in `require' from -e:3:in `<main>' ~~~ while plain Ruby require does not: ~~~ $ ruby --disable-gems -rpathname -e ' pa = Pathname.new("test") require pa ' -e:3:in `require': no implicit conversion of Pathname into String (TypeError) from -e:3:in `<main>' ~~~ This inconsistency is surprising. It seems that RubyGems / Bundler developers think [1] that Ruby `require` should also accept `Pathname`. ~~~ $ ruby -v ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux] ~~~ [1]: https://github.com/rubygems/rubygems/pull/7128 -- https://bugs.ruby-lang.org/
