Я пытаюсь установить гем 'mysql2' на свой рабочий сервер, используя Capistrano.
Я хочу использовать SQLite в разработке и MySQL в производстве.
Я занимаюсь разработкой на компьютере с Windows 7, а в производстве используется Ubuntu.
Когда я запускаю bundle install
на своем компьютере разработчика, он устанавливает MySQL2.
Когда Capistrano запускает его против моей производственной машины, он даже не упоминается в выводе.
Когда я запускаю ту же команду на своей производственной машине прямо в оболочке, она также не упоминает драгоценный камень.
Я также обнаружил, что gem 'therubyracer', :platforms => :ruby
не устанавливается. Я добавил это после записи mysql2. Я надеюсь, что оба связаны. mysql2 не работал до того, как я добавил therubyracer.
В результате всего вышеперечисленного я получаю следующую ошибку при попытке просмотра моего сайта:
Пожалуйста, установите адаптер mysql2: gem install activerecord-mysql2-adapter
(mysql2 не входит в комплект. Добавьте его в Gemfile.)
Дополнительная информация
Я надеюсь, что количество информации, которое я включаю ниже, более полезно, чем боль.
Gemfile
Я ценю, что мог поместить mysql2 в «производство», но это не сработало.
