RubyGems warning/error: Gem::Specification# default_executable = is deprecated with no replacement. It will be removed on or after 2011-10-01.

After recent update of RubyGems (to 1.8), while running for example bundle install, the user will see a bunch of warnings, like:

NOTE: Gem::Specification# default_executable = is deprecated with no replacement. It will be removed on or after 2011-10-01.

This is connected with the recent policy of RubyGems team – read the official statement.

They have deprecated 22+ methods! It will take some time for Gem authors to update… Before then, you may run:

gem pristine --all --no-extensions

to get most recent and thus some of the warrnings gone…

There is a script that tries to substitute deprecated elements:

I hope this helps with annoying warrnings…

..Thanks a lot .. I was getting 15+ warning messages (for most of the rails commands) which was very frustrating, but now I am not getting any warnings at all.
