解决方案： #

• 清除npm缓存并重新安装（需删除锁文件）

  1. 执行命令清除缓存：npm cache clean --force
  2. 删除项目根目录下的node_modules文件夹和package-lock.json文件
  3. 重新安装依赖：npm install

• 手动处理嵌套依赖

  1. 卸载并重新安装raw-body：npm uninstall raw-body && npm install raw-body
  2. 或者直接将iconv-lite安装为顶层依赖：npm install iconv-lite，规避嵌套版本的问题

• 检查并修正iconv-lite的package.json

  1. 进入路径node_modules/raw-body/node_modules/iconv-lite
  2. 打开package.json文件，确认main字段的值为lib/index.js，若不符则手动修改
  3. 保存后重新执行npm run start

• 切换包管理器或源

  1. 切换到国内npm源：npm config set registry https://registry.npmmirror.com/，再重新执行安装
  2. 或者使用yarn替代npm：删除node_modules和package-lock.json，执行yarn install后启动项目
