Question

尝试将Colab Notebook连接到Atlas上的MongoDB。

from pymongo import MongoClient
uri = "mongodb+srv://MYUSERNAME:mypassword@mydatabase.mongodb.net/test"  

client = MongoClient(uri)

我收到CongfigurationError：

"dnspython" module must be installed to use mongodb+srv:// URIs.

我安装了模块。

pip install dnspython

将邮件退回

Requirement already satisfied: dnspython in /usr/local/lib/python3.6/dist-packages (1.16.0)

不知道怎么了。

几天前这与另一个colab笔记本（和另一个数据库）一起使用。

这是整个错误消息：

ConfigurationError                        Traceback (most recent call last)
<ipython-input-30-a6c89e14e64f> in <module>()

ConfigurationError: The "dnspython" module must be installed to use mongodb+srv:// URIs

Answer 1

您必须重新启动运行系统才能使更改生效：

!pip install dnspython
重新启动运行时Runtime -> Restart runtime...
运行代码

Answer 2

尝试安装pymongo [srv]和[tls] !pip3 install pymongo[srv] !pip3 install pymongo[tls]

满足要求时出现ConfigError“必须安装dnspython”
