vite搭建vue2项目的实战过程

npm init vite@2.8.0

// 1.进入项目
cd vite-vue2

// 2.安装依赖
npm install

// 3.启动项目
npm run dev

// 注意：vite-plugin-vue2的版本为1.9.3
npm install vite-plugin-vue2@1.9.3 -D

import { defineConfig } from 'vite' // 动态配置函数
import { createVuePlugin } from 'vite-plugin-vue2'
import { resolve } from 'path'

export default () =>
	defineConfig({
		plugins: [createVuePlugin()],
		server: {
			open: true, //自动打开浏览器
			port: 1567 //端口号
		},
		resolve: {
            // 别名
			alias: [
				{
					find: '@',
					replacement: '/src'
