执行npm install scss安装scss,但是报错
@ ./node_modules/vue-style-loader!./node_modules/css-loader?{“sourceMap”:true}!./node_modules/vue-loader/lib/style-compiler?{“vue”:true,“id”:“data-v-7ba5bd90”,“scoped”:false,“hasInlineConfig”:false}!./node_modules/sass-loader/dist/cjs.js?{“sourceMap”:true}!./node_modules/vue-loader/lib/selector.js?type=styles&index=0!./src/App.vue 4:14-357 13:3-17:5 14:22-365

@ ./src/main.js
@ multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.js

能看出来是少安装了依赖，于是执行 npm install sass-loader --save-dev
但是报错

看起来八成是版本问题，看到网上说npm 版本7要比版本6严格，所以决定把npm 降级到版本6，执行npm install npm@6 -g，npm成功降级，成功安装。但是依然会报错this.getOptions is not a function
八成还是版本问题，卸载sass-loader执行npm uninstall sass-loader
然后安装指定版本的sass-loader@7.3.1和node-sass@4.14.1

npm install sass-loader@7.3.1 --save-dev
npm install node-sass@4.14.1 --save-dev

成功！
