还是不行

> shizhan-vue@1.0.0 build E:\web前段\shizhan-vue

> webpack --mode development

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):

按照大神的方法出现了这个问题，是什么原因怎么破？我试着安装了webpack-cli后报以下错误

Installing 'webpack-cli' (running 'npm install -D webpack-cli')...
