Could not find generator 'flipper:active_record'

[amitmahajan12]

I added the following to my Gemfile:

gem 'flipper'
gem 'flipper-active_record'

Then did bundle install, but after that rails g flipper:active_record doesn't work with the error Could not find generator 'flipper:active_record'

Any idea what the issue could be?

Can you paste your Gemfile.lock or what versions of rails/etc you are using?
