的MongoDB和Django的類型錯誤：__init __（）到底需要2個參數（1給出）

Question

我已經安裝了以下，從link

django-nonrel 

djangotoolbox 

mongodb-engine 

，我改變了我的installed_apps從

INSTALLED_APPS = (
    .. apps .. 
) 

到

INSTALLED_APPS = [ 
    .. apps .. 
] 

但我得到如下錯誤，

Validating models...

我使用的Django 1.5和蟒蛇提前2.7

感謝

django-nonrel是的Django 1.3的一個分支，所以你不能使用Django 1.5中使用它。嘗試卸載Django 1.5。
