一、使用淘宝NPM镜像

（一）为何使用淘宝镜像

国内直接使用npm官方镜像非常慢，推荐使用淘宝NPM镜像，它是一个完整npmjs.org镜像，可用此代替官方版本（只读），目前同步频率为10分钟1次，保证尽量与官方服务同步。

（二）安装淘宝NPM镜像

安装淘宝定制的cnpm，代替替默认的npm
执行命令：npm install -g cnpm --registry=https://registry.npmmirror.com

（三）查看淘宝NPM镜像版本

执行命令：cnpm -v，目前版本是7.1.1

二、使用CNPM安装Vue最新稳定版

在用 Vue.js 构建大型应用时推荐使用cnpm安装，能很好地和Webpack或Browserify模块打包器配合使用

（一）安装Vue最新稳定版

执行命令：cnpm install vue@next

（二）查看Vue命令行工具vue-cli版本

执行命令：vue --version
对于Vue 3，至少应该使用npm上可用的Vue CLI v4.5作为@vue/cli
如果vue cli版本不满足Vue3的条件，那么执行vue upgrade --next升级到最新稳定版

（三）安装全局插件 - @vue/cli-init

执行命令：cnpm i -g @vue/cli-init

三、使用vue init创建Vue项目

（一）初始化Vue项目

执行命令：vue init webpack vue3-demo
