路径解析配置 webpack

const path = require('path')
module.exports = {webpack: {// 配置别名alias: {// 约定： 使用@ 表示src文件所在路径'@': path.resolve(__dirname,'src')}}
}

包文件中配置启动命令和打包命令

{"compilerOptions": {"baseUrl": "./","paths": {"@/*": ["src/*"]}}
}

路径解析配置 Vite

修改Vite配置

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import { resolve } from 'path';export default defineConfig({plugins: [react()],resolve: {alias: {'@': resolve(__dirname, 'src')}}
})

提示：找不到模块‘path’，需安装 

npm i @types/node -D

{"compilerOptions": {"jsx": "react","baseUrl": "./","paths": {"@/*": ["src/*"]}},}
