1、安装node.js
2、npm -v 查看npm版本
3、输入 npm config get registry 检测 npm 默认下载地址
默认应该是 https://registry.npmjs.org/
输入npm config set registry https://registry.npmmirror.com 修改镜像
再使用 npm config get registry 检测
此时就是淘宝镜像下载了 https://registry.npm.taobao.org
4、全局安装 npm install -g @vue/cli，如果报错权限不足前面加sodu
5、如果出现报错，清除缓存 npm clean cache –force
npm error request to https://registry.npm.taobao.org/@vue%2fcli failed, reason: certificate has expired
npm error A complete log of this run can be found in: /Users/wjc/.npm/_logs/2024-08-07T09_02_04_050Z-debug-0.log
