Я не могу установитьstof/doctrine-extensions-bundle с моим композитором. Я использую версию Symfony2.1.9 и много проблем показано. Первый из них:

запрошенный пакет stof / doctrine-extensions-bundle 1.1. * не найден.

Это моеcomposer.json файл:

    }
}

когда я устанавливаю требования к пакету:"stof/doctrine-extensions-bundle": "1.1.*@dev" ответ был:your requirement could not be resolved to an installable set of package

в чем может быть проблема пожалуйста ?? я должен сначала установить DoctrineExtensions ????
