** I installed all the necessary module, but when I want to start the server, then show this message

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

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

instead of those recommended on the Django-Mongodb configuration page. In addition, be sure to use the master branch for each so that there are no compatibility issues. If you use pip , you can either pip install each of the following lines separately, or put them in your version of the 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
