ImportError:无法导入名称SortedDict - 仅在Python 2.7上,而不是2.6

我正在尝试启动并运行Django应用程序.这些库有点过时(目前在Django 1.4上).

当我尝试使用python 2.6时,我或多或少地工作了,但是当我使用python 2.7更改为virtualenv时,我得到错误:

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

我用相同的需求文件设置了virtualenvs.

可能导致此问题的版本之间有什么区别？

SortedDict在Django 1.9中删除了.确保在新虚拟环境中安装了与旧版本相同的Django版本.

如果它是您自己使用的代码SortedDict,那么长期修复就是更新要使用的代码collections.OrderedDict,这是在Python 2.7中添加的.在您的情况下,看起来导入错误来自第三方应用程序,您必须更新或替换它以使代码与Django 1.9一起使用.
