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

ImportError: cannot import name force_text
force_text is a callable within the django. utils. encoding module of the Django project.
force_str is a callable within the django. utils. encoding module of the Django project.
Simply type python -m django --version or type pip freeze to see all the versions of installed modules including Django.
Upgrade to the latest Django 1.4 (as of 07-08-2014 - the "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
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).
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.
Thus, make sure you use latest version of Django
1.4.x and django-debug-toolbar
.
