Question

最近，我尝试将Firebase云功能从javascript迁移到打字稿，然后将功能拆分为多个文件。但是，在尝试服务和部署时会不断出错：

投放时出错：

functions [functionName]：由于Firestore模拟器不存在或未运行，因此忽略了该函数。 functions [functionName]：由于Firebase模拟器不存在或未运行，因此忽略了函数。

部署时出错：

functions[dataDownload(us-central1)]: Deployment error.
Function failed on loading user code. Error message: Code in file lib/index.js can't be loaded.
Is there a syntax error in your code?

尝试过：
Firestore/Firebase Emulator Not Running （安装了模拟器，做了firebase init模拟器）
unable to split Firebase functions in multiple files
Firestore local http with real db: The Cloud Firestore emulator is not running so database operations will fail with a 'default credentials' error

How do I structure Cloud Functions for Firebase to deploy multiple functions from multiple files?
https://javebratt.com/functions-multiple-files/
https://firebase.google.com/docs/functions/typescript#migrating_an_existing_javascript_project_to_typescript

我的目录结构：

--functions
    -- lib
    -- node_modules
    -- src
        -- config
        -- admin.ts
        -- index.ts
        -- dataDownload.ts
    -- tsconfig.json
    -- tslint.json
    -- package.json
    -- package-lock.json

--.firebaserc
-firebase.json
--package.json
--package-lock.json

文件：
index.ts：

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp(functions.config().firebase);

import { dataDownloadHandler } from './dataDownload';
export const dataDownload = functions.firestore.document('user/{uid}/download/{downloadId}').onCreate((snapshot, context) => {
    dataDownloadHandler(snapshot, context);
});

dataDownload.ts：

/* 
imports
*/
export const dataDownloadHandler = (snapshot:any, context:any) => {
    // code
}

当我将dataDownload函数移至dataDownload.ts文件并在export * from './dataDownload;中进行了index.ts时，它也没有起作用。

admin.ts：

import * as admin from 'firebase-admin';

const auth = admin.auth();
const rtDb = admin.database();
const fsDb = admin.firestore();
const firebaseTimestamp = admin.database.ServerValue.TIMESTAMP;
const firestoreTimestamp = admin.firestore.FieldValue.serverTimestamp();

export { admin, auth, rtDb, fsDb, firebaseTimestamp, firestoreTimestamp };

编辑：https个云功能有效； firestore和database云功能没有。

Answer 1

如果您使用的是"fs-extra": "^9.0.0"，请尝试降级到版本8.1.0。

这为我解决了这个问题。

Answer 2

我试图从您的代码示例中复制它，但是一切都已正确部署。

根据此doc（您也提到过），lib / index.js为：

在Firebase部署期间，您项目的index.ts将被转换为index.js，这意味着Cloud Functions日志将输出index.js文件中的行号，而不是您编写的代码。为了使您更轻松地在index.ts中找到相应的路径和行号

所以我想您应该检查那里发生了什么，这些文件在您的身边看起来如何。也许您将能够弄清楚。

我也发现可能有帮助的问题：

class imported but still firebase deploy fails with Cannot find module

Firebase deploy can't find serviceAccountKey

检查您的引用是否不是本地文件，也许您可以尝试在本地重新创建项目并进行部署。希望对您有所帮助！

迁移到打字稿后，Firebase云功能不起作用
