vue3项目打包错误_vue3 打包报错 [commonjs--resolver] failed to resolve e

错误1 包冲突

解决方法两种：
（1）在安装包的时候忽略冲突，安装命令后面加 --force or --legacy-peer-deps 例如：

npm install vue-router@next -S --legacy-peer-deps
1

（2）更新所有的包到，最新，再来解决冲突
npm install -g npm-check-updates // 安装
ncu -u // 检测
npm install // 更新

这个错误似乎是 plugin-legacy 2.0需要 vite 3.0才行

但是我是这样的也报错

这里的解决办法目前只能关闭兼容性

// 3.兼容处理
// import legacy from '@vitejs/plugin-legacy'

 // 兼容性设置
    // legacy({
    //   targets: ['defaults', 'not IE 11']
    // }),

5 node的中使用import引入模块导致错误

import fs from 'node:fs'
import path from 'node:path'
import { fileURLToPath } from 'node:url'

如下错误：

import fs from 'node:fs'
^^^^^^

SyntaxError: Cannot use import statement outside a module

解决方法：
package中添加type:module

"type": "module",
  "scripts": {
    "preview": "vite preview --port 4173",
    "lint": "eslint . --ext .vue,.js,.jsx,.cjs,.mjs --fix --ignore-path .gitignore",
    "dev": "node server",
    "build": "npm run build:client && npm run build:server",
    "build:noExternal": "npm run build:client && npm run build:server:noExternal",
    "build:client": "vite build --ssrManifest --outDir dist/client",
    "build:server": "vite build --ssr src/entry-server.js --outDir dist/server",
    "build:server:noExternal": "vite build --config vite.config.noexternal.js --ssr src/entry-server.js --outDir dist/server",
    "generate": "vite build --ssrManifest --outDir dist/static && npm run build:server && node prerender",
    "serve": "cross-env NODE_ENV=production node server",
    "debug": "node --inspect-brk server",
