如果你安装完 vue-loader vue-template-compiler 执行 npm run dev 时报错如下：
vue-loader was used without the corresponding plugin. Make sure to include VueLoaderPlugin in your webpack config.
Error: vue-loader was used without the corresponding plugin. Make sure to include VueLoaderPlugin in your webpack config.有可能是版本问题。
解决方法：
首先安装：
cnpm i vue-loader vue-template-compiler -D再去webpack.config.js中做相应的配置：
const VueLoaderPlugin = require('vue-loader/lib/plugin')
