使用vue-cli3.0.0脚手架创建的项目，添加px2rem-loader运行报错

添加方法：
按照官方文档https://cli.vuejs.org/guide/webpack.html#simple-configuration
在项目根目录添加vue.config.js并配置：

module.exports = {
  ...
  chainWebpack: config => {
    function generateLoaders (loader) {
      config.module
        .rule(loader)
        .oneOf('vue')
        .use('px2rem-loader')
        .loader('px2rem-loader')
        .options({ remUnit: 75, remPrecision: 8 })
        .end()
      config.module
        .rule(loader)
        .oneOf('normal')
        .use('px2rem-loader')
        .loader('px2rem-loader')
        .options({ remUnit: 75, remPrecision: 8 })
        .end()
    }
    generateLoaders('css')
    generateLoaders('less')
  },
  ...
}

在vue文件写less时编译会报错，而通过<style src="./App.less"></style>的引用可以正常通过
