Issue #21312 has been updated by hsbt (Hiroshi SHIBATA). Thanks! I confirmed `psych` was removed from `rdoc` dependency. I'll look that. ---------------------------------------- Bug #21312: ruby 3.5-dev installs a gemspec for rdoc that misses dependencies https://bugs.ruby-lang.org/issues/21312#change-113670 * Author: deivid (David RodrÃguez) * Status: Assigned * Assignee: hsbt (Hiroshi SHIBATA) * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Similarly to https://bugs.ruby-lang.org/issues/20581, installing ruby 3.5-dev installs a gemspec for rdoc that it's missing its own dependency on psych. This causes issues when using Bundler, as reported at https://github.com/rubygems/rubygems/issues/8637. I created a workaround in Bundler to behave better under this situation and print a warning rather than creating an incorrect lockfile, but ruby installer should fix this too. Thank you! -- https://bugs.ruby-lang.org/
