webpack配置devserve报错 Cannot find module 'webpack-cli/bin/config-yargs'

安装：
npm i webpack-dev-server -S

webpack.config.js:

devServer:{  //实时重新加载
        host:"localhost",
        port:"8081",
        contentBase:"./dist",  //告诉从什么位置查找文件
        compress:true,  //启动gzip压缩
        open:true,  //自动打开浏览器
        hot:true,  //热更新
}

package.json:

"dev": "webpack-dev-server",

解决：

 webpack-cli的新版本对webpack-dev-server版本的不兼容,降低webpack-cli的版本到3.3.12
