路径库：无法从 'collections' 导入名称 'Sequence'
pathlib: cannot import name 'Sequence' from 'collections'
我重建我的项目已经有几天了，但是当我今天早上测试一些东西时，我想更新我的 Werkzeug 包，因为我的 Multidict class，我重建了并开始出现此错误：

如果您查看基本图像，您会发现它刚刚在 27 小时前更新。
$ docker images python:3
REPOSITORY TAG IMAGE ID CREATED SIZE
python 3 618fff2bfc18 27 hours ago 915MB
事实上，从它的 docker hub 来看，python:3 标签现在指向 python 3.10.0，而不是 python 3.9 天前你编写 Dockerfile 的时候。
要解决由第三方库引起的任何不兼容问题，您最好再次将基础映像降级到 python 3.9：
FROM python:3.9
