#### 解决方法 ####

解决的方法我是网上找的，就是把webpack-server降低版本：

npm install webpack-dev-server@2.9.4 --save-dev

--------------------

#### 环境介绍 ####

webpack 4.34.0  
extract-text-webpack-plugin 3.4.0

#### 报错 ####

#### 解决办法 ####

npm install --save-dev extract-text-webpack-plugin@next

--------------------

#### 环境介绍 ####

webpack 4.34.0  
vue-loader 15.7.0

#### 报错 ####

ERROR in ./app.vue?vue&type=style&index=0&id=381730fa&scoped=true&lang=css& 16:3

    File was processed with these loaders:
     * ./node_modules/vue-loader/lib/index.js
    You may need an additional loader to handle the result of these loaders.

#### 解决 ####

npm install --save-dev vue-loader@14.2.4
