windows系统：

webpack4全局安装了webpack、wbpack-cli，局部也安装了webpack、webpack-cli。

命令行运行webpack --mode可以正确打包，

可是 package.json指定配置文件后："build": "webpack --mode poduction --config build/webpack.base.conf.js"   提示：You have installed webpack-cli and webpack-command together. To work with the "webpack" command you need only one CLI package, please remove one of them or use them directly via their binary.
