webpack One CLI for webpack must be installed. These are recommended choices, delivered as separate，webpack报错

用webpack 打包项目的时候:webpack js.js bundle.js 报错.

最近在安装好webpack后，使用时，提示

One CLI for webpack must be installed. These are recommended choices, delivered as separate packages:

- webpack-cli (https://github.com/webpack/webpack-cli)

The original webpack full-featured CLI.

- webpack-command (https://github.com/webpack-contrib/webpack-command)

A lightweight, opinionated webpack CLI.

We will use “npm” to install the CLI via “npm install -D”.

Which one do you like to install (webpack-cli/webpack-command):

我在2018年3月28日的文章“https://blog.csdn.net/jiang7701037/article/details/79403637#commentsedit”也提到了，需要全局安装webpack-cli。虽然这次提示变了，解决方案依然是需要全局安装webpack-cli

如下：

npm install webpack-cli -g

在项目里再做一个本地安装：

npm install webpack -D
