我安装了seaborn Python包并尝试运行first tutorial,它生成了一系列错误。
我做错了什么?我将教程代码复制并粘贴到一个名为www.example.com的文件中seaborn1.py,然后点击运行,得到了这个:

During handling of the above exception, another exception occurred:

你可以进入spotlight(搜索栏)搜索"Install Certificates.command",然后按回车键。

Macintosh HD-> Applications-> Python3.12 -> double click "Install Certificates.command"文件

tl;dr:您的网络堆栈安装缺少必要的根证书。
您对sns.load_dataset("tips")的调用尝试访问https://github.com/mwaskom/seaborn-data下的CSV,具体为https://raw.githubusercontent.com/mwaskom/seaborn-data/master/tips.csv
如果没有DigiCert TLS RSA SHA 256 2020 CA 1证书,这将不会顺利进行。
如果您使用venv、conda或poetry来获取cPython +库,这将非常顺利,而无需给予片刻的考虑。
