To update just one gem  and it s dependencies   do       bundle update gem-name   But to update just the gem alone  without updating it s dependencies   do      bundle update --source gem-name

Or   gem update  gem outdated   cut -d     -f 1

User · Answer

I found other answers to be inaccurate outdated  Best is to refer to the actual documentation   Short version  in most cases gem update --system will suffice   You should not blindly use sudo  In fact if you re not required to do so you most likely should not use it
