Как я могу это исправить, чтобы приложение работало?

Answer 1

Нужно ли устанавливать драгоценный камень непосредственно в каталог вашего приложения Rails?

От здесь:

Плагин Rails

Gruff легко использовать с Rails.

gem install gruff
cd vendor/plugins && gem unpack gruff

Если вы сделали только gem install gruff это может объяснить, что он работает не в рельсах, а в irb.
