Django MongoDB问题

我的django应用程序运行mysql,但当我尝试使用mongodb然后显示该错误

Traceback (most recent call last):

**我已经安装了所有必要的模块,但是当我想要runserver然后显示此消息

我设法通过在github上使用这些包来修复相同的错误:

https://github.com/django-nonrel/django-nonrel
https://github.com/django-nonrel/djangotoolbox

而不是Django-Mongodb设置页面上推荐的那些.另外,请确保使用master每个分支,以免遇到兼容性问题.如果您正在使用pip,您可以pip install单独使用以下每一行,也可以将它们放入requirements.txt您项目的文件版本中:

git+https://github.com/django-nonrel/django-nonrel@master
git+https://github.com/django-nonrel/djangotoolbox@master
git+https://github.com/django-nonrel/mongodb-engine@master

然后运行

pip install -r requirements.txt
