情况说明
今天在装live server时遇到如下两个问题。
- module ‘collections’ has no attribute ‘MutableSet’

部分错误结果如下：

解决方案
网上找了好多都是把问题贴出来然后就没下文了，琢磨了三四个小时幸亏解决了！！应该是python 3.10 那些 MutableMapping，MutableSet等放的位置变了，他们的上级模块原本直属collections的变成了abc，也就是说，需要把
collections.MutableMapping
改成
collections.abc.MutableMapping
那要怎么改呢？文章来源：https://www.toymoban.com/news/detail-538347.html
比如我这里报错，就点进源文件里面
按上述方法修改即可。
