构建webpack项目，但是提示同时安装了 webpack-cli和webpack-command，并让我卸载其中之一

Question

问题描述

执行 npx webpack 的时候他提示我
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.

问题出现的环境背景及自己尝试过哪些方法

我尝试按照他说的卸载其中的webpack-command（npm uninstall webpack-command和npm remove webpack-command都试了）但是没有成功。
我node版本是 v8.11.2
npm版本是 6.4.1
webpack版本4.29.6
webpack-cli版本3.3.0

相关代码

// 请把代码文本粘贴到下方（请勿用图片代替代码）
输入指令： npx webpack

你期待的结果是什么？实际看到的错误信息又是什么？

最后没有成功打包反倒是报了这么个错，到底怎么回事儿

Answer 1

npm uninstall -g webpack-command
