uniapp 小程序prettier代码格式化postcss无法兼容

在进行git hooks的husky时候 postcss只有大于8的版本才可以校验通过

1. 问题1：

1.1、postcss@8编译提示错误文案：
Error: PostCSS plugin postcss-uniapp-plugin requires PostCSS 8.
Migration guide for end-users:
https://github.com/postcss/postcss/wiki/PostCSS-8-for-end-users

1.2、postcss@8 代码自动格式化可以通过

1. postcss@7 本地编译可以正常启动
   2.1、postcss@7 代码格式化提示：
   stylelint --fix --cache:
   TypeError: Class extends value undefined is not a constructor or null
