当我尝试server.js使用 nodemon 运行时出现此错误。我查看了我的node_modules文件夹，那里有一个“曾经”文件夹。我试过了

rm -rf node_modules
npm install

删除整个node_modules文件夹并重新安装，但它没有用。我也做过

npm install --save once

仍然没有工作。

这是 package.json

{
  "name": "FullMean_Friends",
  "version": "0.0.1",
  "scripts": {
    "start": "node server.js"
  },
  "dependencies": {
    "body-parser": "latest",
    "express": "~4.2.0",
    "mongoose": "latest"
  }
}
