HI, i am working in Rails .. my gem list is
*** LOCAL GEMS *** abstract (1.0.0) actionmailer (3.0.4, 3.0.3, 2.3.11, 2.3.10, 2.3.8, 2.3.4, 2.3.2) action
The solution is fairly simple. Just run the following commands to go back to the previous version of rubygems and you should be fine:
$ gem install rubygems-update -v='1.4.2' $ gem uninstall rubygems-update -v='1.5.0' $ update_rubygems
