ImportError：無法導入名稱SortedDict - 只在Python 2.7上，而不是2.6

Question

我試圖讓一個Django應用程序啓動並運行。這些庫有點過時（它目前在Django 1.4上）。

我有或多或少的工作時，我試圖蟒蛇2.6，但是當我使用Python 2.7更改爲virtualenv中我得到的錯誤：

Unhandled exception in thread started by <function wrapper at 0x7f057b17c320>

from django.utils.datastructures import SortedDict 
ImportError: cannot import name SortedDict 

我成立了virtualenvs具有相同要求的文件。

可能導致此問題的版本之間有什麼區別？

Answer 1

SortedDict是removed in Django 1.9。確保你已經在舊虛擬環境中安裝了相同版本的Django。

如果是您自己的代碼使用SortedDict，則長期修復將更新代碼以使用在Python 2.7中添加的collections.OrderedDict。就你而言，看起來導入錯誤來自第三方應用程序，爲了使代碼能夠在Django 1.9上運行，你必須更新或替換它。
