npm run dev后sass报错* !!vue-style-loader!css-loader?{"sourceMap":true}!../../node_modules/vue-loader/l

运行npm run dev后，报错如下：
* !!vue-style-loader!css-loader?{“sourceMap”:true}!../…/node_modules/vue-loader/lib/style-compiler/index?{“vue”:true,“id”:“data-v-41458b80”,“scoped”:true,“hasInlineConfig”:false}!sass-loader?{“sourceMap”:true}!../…/node_modules/vue-loader/lib/selector?type=styles&index=0!./Navbar.vue in ./src/components/Navbar.vue
$npm run dev后sass报错* !!vue-style-loader!css-loader?{"sourceMap":true}!../../node_modules/vue-loader/l$
这是sass编译出现问题只要局部安装sass-loader就可以了：
npm install node-sass sass-loader -D
