ImportError：无法导入名称force_text

I have installed python 2.7 and django 1.4 in my centos machine and installed all dependencies for my existing project.When i run "python manage.py runserver" i am getting the following traceback in my console.

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

Upgrade to the latest Django 1.4 (as of 07-08-2014 - the "1.4.13").

升级到最新的Django 1.4(截至2014年7月7日 - “1.4.13”)。

I see that they have added a shortcut (force_text) in the django.utils.encoding module: https://github.com/django/django/blob/stable/1.4.x/django/utils/encoding.py

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

Note, that the shortcut wasn't there in the initial 1.4 version (https://github.com/django/django/blob/1.4/django/utils/encoding.py) and was only added in 1.4.2 (https://github.com/django/django/blob/1.4.2/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)。

As stated in the docs of django-debug-toolbar, current version (as of 07-08-2014 - the "1.2.1") works fine on Django 1.4 to 1.7.

正如django-debug-toolbar的文档中所述,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。

Thus, make sure you use latest version of Django 1.4.x and django-debug-toolbar.

因此,请确保使用最新版本的Django 1.4.x和django-debug-toolbar。
