I added best_in_place to my GemFile, ran bundle install and the gem does not appear on the list that shows "Using...". But best_in_place does show in gem list.
When I try to use best_in_place in my app, I get undefined method best_in_place.
I do have a GemFile.lock.
Restart your Rails server, if you are working on Rails 4 , add
gem 'best_in_place', github: 'aaronchi/best_in_place'into yourGemfilethen runbundle install
