Firebase 在子文件夹中导入模块后，云功能未正确部署

Question

我在部署 Firebase Cloud Functions 时遇到问题，因为它找不到导入的本地模块。

这是部署命令的 output

> firebase deploy --only functions
> build
> tsc

✔  functions: Finished running predeploy script.
i  functions: ensuring required API cloudfunctions.googleapis.com is enabled...
i  functions: ensuring required API cloudbuild.googleapis.com is enabled...
✔  functions: required API cloudbuild.googleapis.com is enabled
✔  functions: required API cloudfunctions.googleapis.com is enabled
i  functions: preparing functions directory for uploading...
i  functions: packaged functions (69.03 KB) for uploading
i  scheduler: ensuring required API cloudscheduler.googleapis.com is enabled...
i  pubsub: ensuring required API pubsub.googleapis.com is enabled...
✔  scheduler: required API cloudscheduler.googleapis.com is enabled
✔  pubsub: required API pubsub.googleapis.com is enabled
✔  functions: functions folder uploaded successfully
i  functions: updating Node.js 12 function myFunctionName(us-central1)...
i  functions: scheduler job firebase-schedule-myFunctionName-us-central1 is up to date, no changes required
✔  functions[myFunctionName(us-central1)]: Successful upsert schedule operation. 

Functions deploy had errors with the following functions:
        myFunctionName(us-central1)

To try redeploying those functions, run:
    firebase deploy --only "functions:myFunctionName"

To continue deploying other features (such as database), run:
    firebase deploy --except functions

Error: Functions did not deploy properly.

我尝试运行firebase --debug deploy但它没有提供有用的信息，而是将我发送到 Firebase 控制台中的日志。

Provided module can't be loaded.
Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module './module/MyModule'
Could not load the function, shutting down.

Error: function terminated. Recommended action: inspect logs for termination reason. Additional troubleshooting documentation can be found at https://cloud.google.com/functions/docs/troubleshooting#logging Function cannot be initialized.

正如您在下面的代码中看到的， MyModule是一个导入的本地模块。

文件夹结构（使用firebase init创建）

root
│   firebase.json
│   ...
│
└───functions
    │   package.json
    │   node_modules
    │   ...
    │
    └───src
        │   index.ts
        └───module
            │   MyModule.ts

索引.ts

import * as functions from "firebase-functions";
import { MyClass } from "./module/MyModule";

export const myFunctionName = functions.pubsub
  .schedule("every 5 minutes")
  .onRun(async () => {
    const myClass = new MyClass();
    const result = await myClass.doSomething();
    functions.logger.log("something has done!", result);
    return result;
  });

./module/MyModule.ts

export class MyClass {
  async doSomething() {
    // Do Something
  }
}

package.json

{
  "name": "functions",
  "scripts": {
    "lint": "",
    "build": "tsc",
    "serve": "npm run build && firebase emulators:start --only functions",
    "shell": "npm run build && firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "12"
  },
  "main": "lib/index.js",
  "dependencies": {
    "firebase-admin": "^9.2.0",
    "firebase-functions": "^3.11.0",
    "googleapis": "^80.1.0"
  },
  "devDependencies": {
    "firebase-functions-test": "^0.2.0",
    "typescript": "^3.8.0"
  },
  "private": true
}

我努力了

• 在本地测试运行 function（它确实有效！）
• 再次运行deploy命令前先删除Firebase Console中的function
• 删除node_modules ，再次运行npm install

不确定是什么导致了问题。 为什么找不到本地模块？

更新

我试图将MyModule.ts移动到与index.ts相同的级别并且它确实部署了！

所以它看起来像这样：

root
│   firebase.json
│   ...
│
└───functions
    │   package.json
    │   node_modules
    │   ...
    │
    └───src
        │   index.ts
        │   MyModule.ts

import * as functions from "firebase-functions";
import { MyClass } from "./MyModule"; // Updated import

export const myFunctionName = functions.pubsub
  .schedule("every 5 minutes")
  .onRun(async () => {
    const myClass = new MyClass();
    const result = await myClass.doSomething();
    functions.logger.log("something has done!", result);
    return result;
  });

但它仍然困扰着我为什么不能从子文件夹导入模块？ 因为我的项目文件比较多，想整理一下。

Answer 1

我想到了。 我注意到我有 2 个函数都有类似的实现，但导入了不同的模块，只有 1 个函数会导致部署错误。

然后我想起我最近将有问题的模块从myModule.ts重命名为MyModule.ts但 Visual Studio Code 仍然将其视为myModule.ts但代码仍然运行（本地）所以我忽略了它。

如果您认为您的问题与我的类似，您可以执行以下操作。

• 将有问题的文件重命名为其他名称。
• （如果您想保留名称）删除您的存储库（本地）并再次克隆它。

Answer 2

我遇到了同样的问题，只需运行即可解决：

firebase deploy --only "functions:FunctionNameHere"
