npm WARN [email protected] requires a peer of [email protected] but none is installed. You must install

安装webpack和webpack-cli时出现的问题:
npm WARN [email protected] requires a peer of [email protected] but none is installed. You must install peer dependencies yourself.

问题翻译::
NPMWA [email protected]需要一个[email protected]的对等点，但没有安装。您必须自己安装对等依赖项。

原因:
安装时命令:npm install webpack -g
npm install webpack-cli -g
默认安装了webpack最新版本,导致安装的最新脚手架webpack-cli与webpack版本不匹配,导致安装错误
解决:

1. 指定webpack安装版本:

			npm install [email protected] -g

2. 指定webpack安装的版本如下:

			npm install [email protected] -g

3. 安装成功:

PS D:\developer\IdeaProjects\itcast-nodejs> npm install [email protected] -g
