sass和sass-loader相关报错

1. math.div

Error: Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
SassError: Undefined function.
  ╷

  │                 ^^^^^^^^^^^^^^^^

sass版本太低，更新版本为以下

"sass": "^1.39.2",
"sass-loader": "^10.1.1",

2. TypeError: this.getOptions is not a function 之前安装sass-loader版本太高（12.3.0） 退回10.1.1即可
