如何在 Django 框架和 Python3 中使用 MongoDB

Question

我是 python、django 和 mongoDB 世界的新手。我已经设置了 Django 项目（Virtualenv、Python3、Django==1.10.1 MongoDB）并安装了一些基本的包要求：

Django==1.10.1
django-mongodb-engine==0.6.0
djangotoolbox==1.8.0
mongoengine==0.9.0
pymongo==3.3.0

但是当我尝试使用python3 manage.py syncdb 同步db 时，它会显示

~/virtenv/lib/python3.5/site-packages/django_mongodb_engine/base.py", line 272
    raise ImproperlyConfigured, exc_info[1], exc_info[2]
                              ^
SyntaxError: invalid syntax
