1.Node 下载安装
下载网址：https://nodejs.org/dist/v20.9.0/node-v20.9.0-x64.msi
下载完毕点击安装包 然后一路默认选项 Next …
2.Node验证是否安装成功
npm -v
node -v
Microsoft Windows [版本 10.0.22631.2428](c) Microsoft Corporation。保留所有权利。
C:\Users\liuzhengquan.cn>npm -v
10.2.3
C:\Users\liuzhengquan.cn>node -v
v20.9.0
C:\Users\liuzhengquan.cn>
3.设置文件存放路径(可选操作，随意,不操作则会自动使用默认路径存储)
3.1 查看默认路径命令：
# 获取下载依赖包路径
npm config get prefix
# 获取缓存路径
npm config get cache
3.2 如果需要更改可以在其它磁盘找个位置，创建两个文件夹，公共下载依赖存储文件夹 和 缓存文件夹
3.3 更新默认设置node路径配置

C:\Users\liuzhengquan.cn>npm config get prefix
C:\Program_Files\Environment_Dependency_Cache_Package\Node\Repository\global
C:\Users\liuzhengquan.cn>
4.配置更新修改环境变量
4.1 新建配置【系统】环境变量
4.2 编辑新增【系统】环境变量
4.3 校验配置是否成功
cmd 中执行任意 npm 依赖包 这里以 express 演示
npm install express -g

5.4.4 如何使用cnpm
# cnpm install 需要下载的依赖包名称# 比如# npm install express -g 改使用cnpm 国内镜像则为这样 cnpm install express -g
6.npm / cnpm 常用命令参考指南大全
6.1 下载安装全局包
npm install -g <package_name>
6.2 卸载本地包
6.2.1 无作用域包
npm uninstall <package_name>
6.2.2 有作用域包
npm uninstall <@scope/package_name>
6.3 卸载全局包
6.3.1 无作用域包
npm uninstall -g <package_name>
6.3.2 有作用域包
npm uninstall -g <@scope/package_name>
6.4 更新依赖包 (本人觉得没必要，因为直接卸载再下载安装更有灵魂，有需要的自己度娘…)
