settings.DATABASES 配置不正确使用 django 1.4 执行 syncdb 时出错

我已经创建了一个简单的Django 1.4项目，并且正在try 发出syncdb来创建(Postgres)数据库模式.我收到这个错误:-

Traceback (most recent call last):
File "manage.py", line 10, in <module>
execute_from_command_line(sys.argv)

raise ImproperlyConfigured("settings.DATABASES is improperly configured. "
django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured.Please supply the ENGINE value. Check settings documentation for more details.

我的settings.py文件如下所示:-

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'test',                      # Or path to database file if using sqlite3.
        'USER': 'test',                      # Not used with sqlite3.
        'PASSWORD': 'test',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
     }
}

我可以使用psql OK连接到数据库-有什么 idea 吗？提前谢谢！
