更新Vue项目package.json文件方式

npm init -y     # 先生成基础 package.json（如果没有的话）
npm install --package-lock-only  # 确保 lock 文件是最新的
npx depcheck    # 可选，查看未使用的依赖

npx npm-dedupe
npx modclean   # 清理无用文件（可选）

const fs = require('fs');
const path = require('path');
const child_process = require('child_process');

const nodeModulesPath = path.resolve('node_modules');
const allDeps = fs.readdirSync(nodeModulesPath).filter(name => name !== '.bin');
const dependencies = {};

allDeps.forEach(pkg => {
  try {
    const pkgPath = path.join(nodeModulesPath, pkg, 'package.json');
    const pkgJson = JSON.parse(fs.readFileSync(pkgPath, 'utf-8'));
    dependencies[pkg] = pkgJson.version;
  } catch (e) {
    console.warn(`跳过无效包: ${pkg}`);
  }
});

const newPkgJson = {
  name: "recovered-project",
  version: "1.0.0",
  description: "",
  main: "index.js",
  scripts: {},
  dependencies,
};

fs.writeFileSync('package.recovered.json', JSON.stringify(newPkgJson, null, 2));
console.log('已生成 package.recovered.json');
