Hi, all when i type command ''gem list'' it will show me the list as the following: *** LOCAL GEMS *** abstract (1.0.0) actionmailer (3.0.9) actionpack (3.0.9) activemodel (3.0.9) activerecord (3.0.9) activeresource (3.0.9) activesupport (3.0.9) arel (2.0.10) builder (2.1.2) bundler (1.0.15) .... ... So, i want to uninstall everything in the list , in other words, remove everything in local repository of gems, but i don''t want uninstall it one by one with that original command. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
