这里.使用mongoengine 0.10时，我们可以看到/usr/lib/python2.7/site-packages/mongoengine/中没有django软件包.使用sudo pip install mongoengine == 0.9安装mongoengine 0.9，并且django软件包(支持或扩展)将可用.

this is answered here. with mongoengine 0.10 we can see that /usr/lib/python2.7/site-packages/mongoengine/ will not have django package in it. Install mongoengine 0.9 using sudo pip install mongoengine==0.9 and the django package (support or extension) will be available.
