最开始以为是缺少python2.7

安装了 python2.7 和 windows-build-tools以后依然报错

原因分析：

node-sass和 node版本不对应

我之前的node-sass版本是4.7.2

NodeJS	Supported node-sass version	Node Module
Node 17	7.0+	102
Node 16	6.0+	93
Node 15	5.0+, <7.0	88
Node 14	4.14+	83
Node 13	4.13+, <5.0	79
Node 12	4.12+, <8.0	72
Node 11	4.10+, <5.0	67
Node 10	4.9+, <6.0	64
Node 8	4.5.3+, <5.0	57
Node <8	<5.0	<57

解决方案：

node-sass 版本修改6.0.1

在执行 npm install
