Question

Я не могу заставить MySQL работать с моим новым приложением rails ... терминал ниже:

и я тоже попробовал:

Janes-MacBook-Pro:hello janelee$ gem uninstall sqlite3

You have requested to uninstall the gem:

If you remove this gems, one or more dependencies will not be met.

Что еще мне следует попробовать перед переустановкой Lion?

Answer 1

Изучите использование Ruby Version Manager (называемого rvm), а затем обновите Ruby. Попробуйте использовать версию 1.9 рубина или выше. Не переустанавливайте свою ОС. Если что, удалите рельсы, удалите рубин. Установите rvm, установите ruby ​​1.9, установите рельсы. Если вы следуете этому рецепту, все должно быть хорошо.

Настройка Rails для работы с MySQL произойдет путем изменения файла:

myappname/config/database.yml  

Хорошая информация здесь: Как установить MySQL в качестве базы данных по умолчанию в Rails 3?

... и здесь: Создайте новое приложение Ruby on Rails, используя MySQL вместо SQLite

Привыкайте смотреть на путеводители по Rails. Примеры, подобные этому: http://guides.rubyonrails.org/getting_started.html#configuring-a-database - это все, что вам нужно для начала работы.
