Node.js AWS Lambda错误“；找不到模块'；mongodb'&引用；

我已成功地将我的功能部署到AWS

尝试调用函数（

serverless invoke-f facebookAdInsert-l

）时，出现以下错误：

{
    "errorMessage": "Cannot find module 'mongodb'",
    "errorType": "Error",
    "stackTrace": [
        "Function.Module._load (module.js:474:25)",
        "Module.require (module.js:596:17)",
        "require (internal/module.js:11:18)",
        "Object.<anonymous> (/var/task/src/facebookAdInsert.js:222:18)",
        "__webpack_require__ (/var/task/src/facebookAdInsert.js:20:30)",
        "Object.<anonymous> (/var/task/src/facebookAdInsert.js:234:16)",
        "__webpack_require__ (/var/task/src/facebookAdInsert.js:20:30)",
        "Object.<anonymous> (/var/task/src/facebookAdInsert.js:303:16)",
        "__webpack_require__ (/var/task/src/facebookAdInsert.js:20:30)"
    ]
}

有没有关于这个问题的想法？根据我的研究，可能的解决方案是在部署所有“依赖项”并将其移动到“依赖项”之前运行

npm install

，但这些都不起作用。

您缺少AWS lambda的mongodb层

打开一个终端并键入

mkdirnodejs

cd节点

npm init-y

npm安装mongodb

压缩整个nodejs文件夹，确保如果解压缩该文件夹，将获得以下结构

将此层上载到AWS Lambda

将图层添加到Lambda函数中

有了这个，它应该可以毫无问题地工作
