Question

我正在尝试为Django + MongDB + Mongodbengine设置环境。但是，我仍然收到错误，

django.core.exceptions.ImproperlyConfigured：＆＃39; django_mongodb_engine＆＃39; 不是一个可用的数据库后端。

我使用以下命令启动服务器：

Start server: python3 manage.py runserver

我在虚拟环境中使用Python 2.7.10，而我的requirements.txt是：

Django==1.7.11 
djangotoolbox==1.8.0 
mongoengine==0.13.0 
pymongo==2.8
pyserial==3.1.1 
requests==2.13.0 
six==1.10.0 
wheel==0.24.0

Manager.py

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "backend_server.settings")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)

这是setting.py

我在互联网上搜索了解决方案，但没有得到解决方案。版本有问题吗？我该如何纠正它们？

Answer 1

解决方案是我将网站转移到MEAN Stack，我认为它是MongoDB的一个很好的平台。但是，如果有人找到Mongoengine产品的版本解决方案，欢迎发布您的答案，谢谢。

django_mongodb_engine配置不当
