迁移到typescript后，Firebase云功能无法工作

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。然而，我在尝试服务和部署时不断出错：

服务时出错：

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

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函数移到dataDownload.ts文件中并在index.ts中执行export * from './dataDownload;时，它也不起作用。

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 };

Answer 1

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

这为我解决了问题。

Answer 2

我试图从您的代码示例中复制它，但一切都部署得很好。

根据这个文档(你也提到过(lib/index.js是：

在firebase部署期间，您的项目的index.ts被转换为index.js，这意味着云函数日志将输出index.js文件中的行号，而不是您编写的代码。为了让您更容易在index.ts中找到相应的路径和行号

所以我想你应该检查一下那里发生了什么，这些文件在你这边看起来怎么样。也许你会想明白的。

此外，我还发现了一些可能有用的问题：

类已导入，但仍有firebase部署失败，无法找到模块

Firebase部署可以'；找不到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，然后进行部署。我希望这会有所帮助！
