我正在关注 w3schools 的 python 教程。我刚刚开始了 mongoDB 章节。我安装了 mongoDB 并检查了它：

import pymongo 

没有得到错误。

但是一旦我输入以下代码：

import pymongo

myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
mydict = { "name": "John", "address": "Highway 37" }

x = mycol.insert_one(mydict)

print(x.inserted_id)

我在 cmd 底部收到这些消息和错误消息：

    C:\Users\xxx\myname

    C:\Users\xxx\myname>python index.py
    Traceback (most recent call last):
