1.查看你的package.json文件

看你是否安装了less

"less": "^3.12.2",
"less-loader": "^4.1.0",

1.1安装less

用cnpm或者npm都可以

npm install less less-loader --save

1.2 打开build目录

在【build】文件下的【webpack.base.conf.js】文件中【rules】中加入

{
    test: /\.less$/,
    loader: "style-loader!css-loader!less-loader"
}

（根据自己需求）在你自己页面【style】标签里面写上【lang=“less”】

<style lang="less">
  industry-pro{width: 100%; height: 600px;}
</style>

1.3 下载依赖

cnpm i

1.4 然后启动项目

cnpm run dev

2 (loaderContext.getResolve is not a function问题解决)

2.1 降低版本(解决问题)

然后修改版本

cnpm run dev

2.2 修改完成以后，重新执行命令

cnpm i

然后启动项目

3 问题解决
