我完全按照本教程进行操作。尝试使用 virtualenv 多次删除和重新启动，但仍然出现错误。设置 python、mongodb 和 django 是否应该如此令人沮丧？

http://docs.mongodb.org/manual/tutorial/write-a-tumblelog-application-with-django-mongodb-engine/

我尝试打电话时遇到问题

post.save()

然后我得到这个错误：

Traceback (most recent call last):

    from bson.objectid import ObjectId

请有人引导我朝着正确的方向前进。有没有更好的教程可以遵循，因为我遵循的每一个教程都会遇到错误。我即将放弃 pymongo 和 django ......

看起来环境设置不正确。您能否确保 pymongo 在您的 python shell 中可用：

$> python.exe

然后在外壳中：

>>> import pymongo
>>> pymongo.version

该报告是什么版本？

也尝试导入 bson：

>>> import bson

如果这些工作，那么请确保您在相同的环境中运行您的 django mongodb-engine 应用程序。
