部署到 Firestore Cloud Functions - “错误：找不到模块”

Question

我在尝试部署函数时得到这个：

Deployment error.
Build failed: npm ERR! code ENOLOCAL
npm ERR! Could not install from "../config/myconfig" as it does not contain a package.json file.

这是在 按照官方文档的建议更新我的functions目录中的package.json ，如下所示：

...
"dependencies": {
    "sms_sender": "file:./",
    "myconfig": "file:../config/myconfig",
    "firebase-admin": "^8.10.0",
    "firebase-functions": "^3.6.1"
  },
...

这应该可以修复此错误，如 GCP 日志上的堆栈跟踪所示：

sendMessage 是我在 index.js 中的后台函数，它导入了“sms_sender”模块：

exports.sendMessage = functions.https.onRequest(async (req, res) => {
  ...
  // send the sendMessage
  sms_sender.sendMsg("+123567890", "hello, my friend!");
  ...
}

sms_sender.js：

const config = require('../config/myconfig');

module.exports = {
  sendMsg: async function(recipientNum, message) {
    ...
  }
}

项目结构：

/project-root
    /config
        myconfig.js
    /functions
        index.js
        sms_sender.js
        package.json
    /tests
    ...
    package.json

我看了这个相关的帖子，但它在谈论外部依赖。

我应该如何告诉 Node/npm 'myconfig' 只是一个本地文件，而不是一个真正的模块本身？ 我尝试将存根 'package.json' 文件放入 /config 但我仍然得到相同的Could not install from "../config/myconfig" as it does not contain a package.json file. 错误

Answer 1

确保您从功能目录而不是项目目录安装了包。 它在本地工作并在您部署时产生错误。 所以，

cd functions
npm install [your package]

它会正常工作

Answer 2

您需要在functions目录中包含您想要的所有文件，因为只有这些文件被打包并上传以创建Cloud Function 的源代码。如果您将config移动到functions目录中，您应该有更好的运气。

Answer 3

这个关于 Firebase 工具存储库的相关讨论有点帮助，但最流行的答案（在./functions目录下创建一个 tarball）对我来说不太适用。

什么工作：在./functions内创建根级./config文件夹的符号链接：

cd functions
ln -s ../config/ config

此策略将config所有文件都用于功能模块，而不会导致我重新编写应用程序的所有其他部分，这些部分中继所描述的文件/文件夹结构

我必须做的唯一其他更改：

// functions/package.json
...
"dependencies": {
    "sms_sender": "file:./",
    "myconfig": "file:./config/",
    "firebase-admin": "^8.10.0",
    "firebase-functions": "^3.6.1"
  },
...

和

// sms_sender.js
const config = require('./config/myconfig');
... // everything else is as before
