2、错误原因

     在使用webpack对JavaScript文件打包时，先是提示这个

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):

     选择了webpack-cli，进行了安装
