推荐答案

我通过在github上使用以下软件包设法解决了相同的错误:

I managed to fix the same error by using these packages on github:

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，请确保使用每个master分支，以免遇到兼容性问题.如果您使用的是pip，则可以分别pip install以下各行，或将其放入项目的requirements.txt文件版本中:

instead of the ones recommended on Django-Mongodb's setup page. Also, make sure to use the master branch of each, so as to not run into compatibility problems. If you're using pip, you can either pip install each of the following lines separately, or put them into your version of a requirements.txt file for your project:

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
