ошибка yii при выполнении специальной команды

Ниже приведена нижеприведенная ошибка при запуске моей пользовательской команды yiic в терминале.

Я не могу понять причину этой ошибки, может ли кто-нибудь указать мне в правильном направлении. Я знаю, что БД работает нормально, так как другие части приложения работают.

• Yii и нокаут вместе?
• YII - как мы можем получить имя метода в функции init () в контроллере?
• Наследование Php, динамические свойства и новый статический () конструктор
• Как авто Войти и перенаправление после регистрации в yii?
• Ошибка при загрузке изображения Yii
• контроллер существует, но страница не найдена
