** I have installed all necessary module installed, but when i want to runserver then show this message

Answer 1

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

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

And then run

pip install -r requirements.txt
