javascript - 运行 Node 脚本时出错，找不到模块 'mongodb/node_modules/bson'

Question

尝试在 mongoose 的帮助下用员工数据填充 mongo 数据库。当运行为:node populate_db.js 时，它会抛出一个错误，指出

module.js:471
    throw err;
    ^

Error: Cannot find module 'mongodb/node_modules/bson' 

无法检查数据库值，因为数据库似乎也是空的。

这是我的 package.json 文件:

{
  "name": "hr",
  "version": "1.0.0",
  "description": "first node app server",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

您可以直接在包 json 文件中将 mongoose 更改为版本 4.2.9。在编辑器中启动 json 文件并将版本更改为“this”。在您拥有项目文件夹的目录中输入“npm install”。
