не может активировать Bcrypt-рубин (~> 3.0.0), уже активированная Bcrypt-рубин-3.1.2

Question

Когда я пытаюсь запустить heroku run rake db:migrate я получаю эту ошибку:

can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.2. Make sure all dependencies are added to Gemfile.

Я обновленное мой Gemfile и указали версию bcrypt, но не сработали. Все находится на правильной ветке.

Gemfile:

Попробуйте использовать

gem 'bcrypt-ruby', '~> 3.0.0'
