我正在开发vue应用程序。一切都很好，直到我用Vuex商店替换了静态商店。

当我执行npm run dev时，出现以下错误:

These dependencies were not found: 
* !!vue-style-loader!css-loader?{"sourceMap":true}!../node_modules/vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-7ba5bd90","scoped":true,"hasInlineConfig":false}!sass-loader?{"sourceMap":true}!../node_modules/vue-loader/lib/selector?type=styles&index=0!./App.vue in ./src/App.vue 
* vue-material in ./src/main.js 
* vue-material/dist/theme/default-dark.css in ./src/main.js 
* vue-material/dist/vue-material.min.css in ./src/main.js, ./node_modules/babel-loader/lib!./node_modules/vue-loader/lib/selector.js?type=script&index=0!./src/components/StepperMotor.vue 

请您参考如下方法:

安装那些依赖

npm i --save vue-style-loader .  
npm i --save css-loader
