“bootstrap3”不是有效的标签库：ImportError raise loading loading bootstrap3.templatetags.bootstrap3: cannot import name force_text

Question

我正在通过这个链接浏览关于 django-bootstrap 的教程：“https://pypi.python.org/pypi/django-bootstrap3https://pypi.python.org/pypi/django-bootstrap3”

在我的 settings.py 中：

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'myapp',
# Uncomment the next line to enable the admin:
'django.contrib.admin',
'example_app',
'southtut',
'south',
'bootstrap3',
# Uncomment the next line to enable admin documentation:
# 'django.contrib.admindocs',

)

在我的模板中：

我写了

 {% load bootstrap3 %}

但我在模板中的上述行中得到以下内容，例如：

TemplateSyntaxError at /myapp/product/

我不知道我错在哪里。请帮帮我

这里的错误是“无法导入名称 force_text”，这是因为您使用的是 Django 1.4
