vue框架中窍奋，使用webpack打包vue項(xiàng)目，在執(zhí)行npm run start的時(shí)候 出現(xiàn)如下錯(cuò)誤：
!!vue-style-loader!css-loader?{"minimize":false,"sourceMap":false}!../../node_modules/vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-1d57e5ea","scoped":false,"hasInlineConfig":false}!stylus-loader?{"sourceMap":false}!../../node_modules/vue-loader/lib/selector?type=styles&index=0!./a.vue in ./src/components/a.vue
To install it, you can run: npm install --save !!vue-style-loader!css-loader?{"minimize":false,"sourceMap":false}!../../node_modules/vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-1d57e5ea","scoped":false,"hasInlineConfig":false}!stylus-loader?{"sourceMap":false}!../../node_modules/vue-loader/lib/selector?type=styles&index=0!./a.vu
解決辦法：
npm install sass-loader --save-dev;
npm install node-sass --save-dev;
然后運(yùn)行npm run start就可以 了
