Firebase 云功能在迁移到打字稿后不起作用

Question

最近，我尝试将我的 firebase 云函数从 javascript 迁移到 typescript，并将这些函数拆分为多个文件。但是，在尝试提供服务和部署时，我不断收到错误消息：

服务时的错误：

函数[functionName]：函数被忽略，因为 Firestore 模拟器不存在或未运行。函数[functionName]：函数被忽略，因为 firebase 模拟器不存在或未运行。

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?

      } catch {
              ^

尝试过：
Firestore/Firebase 模拟器未运行 （安装了模拟器，做了 firebase init 模拟器）
无法在多个文件中拆分 Firebase 函数
Firestore local http with real db：Cloud Firestore 模拟器未运行，因此数据库操作将因“默认凭据”而失败' 错误

如何构建 Cloud Functions for Firebase 以从多个文件部署多个函数？
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);
});

数据下载.ts：

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

当我将dataDownload函数移入 dataDownload.ts 文件并export * from './dataDownload;在index.ts.

管理员：

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云功能工作；firestore而database云功能则不然。

如果您正在使用"fs-extra": "^9.0.0"尝试降级到版本8.1.0。

这为我解决了问题。
