该路径下运行cmd,执行以下命令:
查看node版本
`node -v`
查看npm版本
`npm -v`

如果不想把npm全局模块和cache目录放到用户目录下(一般是C:\Users\AppData),建议修改一下两个目录。
在自定义位置创建node_cache和node_global两个文件夹
```bash
npm config set prefix D:\Data\Node\node_global
npm config set cache D:\Data\Node\node_cache
```

测试
测试并安装淘宝NPM镜像
因为npm下载资源来源国外,网络不稳定,下载也慢,安装了淘宝的镜像后使用国内cnpm资源会变得非常快。
在cmd命令提示符中输入下面的命令:
`npminstall-gcnpm--registry=https://registry.npm.taobao.org`
