Resolving dependencies... Could not find compatible versions Because every version of activerecord depends on activesupport = 8.2.0.alpha and activesupport = 8.2.0.alpha could not be found in rubygems repository https://rubygems.org/ or installed locally, activerecord cannot be used. So, because Gemfile depends on activerecord >= 0, version solving has failed. $ ``` ### Did you try upgrading rubygems & bundler? Yes. ``` $ ruby -v ruby 4.0.4 (2026-05-12 revision b89eb1bcbf) +PRISM [x86_64-linux] $ gem -v 4.0.11 $ bundler -v 4.0.11 $ BUNDLE_ONLY=ci bundle install Fetching https://github.com/rails/rails.git Fetching gem metadata from https://rubygems.org/...........
