sh: webpack-dev-server: command not found 错误

公司的项目前端代码，技术栈用的是react+dva+react-router+antd，没有采用服务器端渲染，拉下来后npm install,太慢了，换了cnpm install，安装完成。

"dev": "webpack-dev-server --progress --config ./webpack.dev.config.js",

然后npm run dev，报错

我看网上有人说需要把 webpack-dev-server 全局安装，然后把webpack-dev-server放在命令行配置的路径中，我感觉这种做法不太好。

贴一下项目的依赖配置

 "dependencies": {
    "antd": "^2.12.1",
    "babel-runtime": "^6.9.2",
