Question

我正在尝试学习如何在Python中使用MongoDB，但是每次我运行代码时，都花了很长时间，我不得不将其杀死，并且得到了这些回溯。

    gotit = waiter.acquire(True, timeout)
KeyboardInterrupt

Process finished with exit code 1

这是我的代码：

import pymongo

client = pymongo.MongoClient("localhost", 27017)
database = client["database"]
high_scores = database["highscore"]

mydict = {"highscore" : 5}
x = high_scores.insert_one(mydict)
print(x.inserted_id)

我的信念是它无法连接到本地主机

Answer 1

显然mongodb没有在我的PC上启动。我要做的就是跑步

brew services start mongodb

效果很好。

PyMongo-本地主机上的服务器超时
