ImportError:无法导入名称force_text

我在我的centos机器上安装了python 2.7和django 1.4并为我现有的项目安装了所有依赖项.当我运行"python manage.py runserver"时,我在我的控制台中获得了以下回溯.

[root@localhost bv]# python manage.py runserver

升级到最新的Django 1.4(截至2014年7月7日 - "1.4.13").

我看到他们force_text在django.utils.encoding模块中添加了一个快捷方式():https: //github.com/django/django/blob/stable/1.4.x/django/utils/encoding.py

请注意,最初的1.4版本(https://github.com/django/django/blob/1.4/django/utils/encoding.py)中没有该快捷方式,并且仅在1.4.2中添加了该快捷方式(https: //github.com/django/django/blob/1.4.2/django/utils/encoding.py).

正如文档中所述django-debug-toolbar,当前版本(截至2014年7月7日 - "1.2.1")在Django 1.4到1.7上运行良好.

因此,请确保使用最新版本的Django1.4.x和django-debug-toolbar.
