I elaborated a version to cleanup only old versions of the gems:

#!/bin/sh RBENVPATH=`rbenv root` echo $RBENVPATH RUBIES=`ls $RBENVPATH/versions` for ruby in $RUBIES; do echo '---------------------------------------' echo $ruby rbenv local $ruby gem cleanup done

nice script, thank you

Updated solution needed, because of the following header:

*** LOCAL GEMS ***

*** LOCAL GEMS *** aasm (5.3.0) abbrev (default: 0.1.1) ace-rails-ap (4.3) etc...

Fix:

--no-verbose is what removes the header.
(We may need another fix in the future if things change again)

#!/bin/bash gem_remove() { gem list --no-versions --no-verbose | xargs gem uninstall -aIx gem list } gem_remove_all() { #rbenv versions --bare RBENVPATH=`rbenv root` echo $RBENVPATH RUBIES=`ls $RBENVPATH/versions` for ruby in $RUBIES; do echo '---------------------------------------' echo $ruby rbenv local $ruby gem_remove done }

I don't include gem install bundler at the end.
Many times in Rails, Gemfile.lock will include a specific bundler version, so I prefer to just install that version manually.
