【问题描述】：

我在部署谷歌云功能时遇到错误 - 使用 firebase（之前它工作正常，但突然开始出现此错误，所以我删除了整个文件夹并再次执行该过程但仍未解决）

index.js

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const db = admin.firestore();
.
.
.

控制台

✔  functions: Finished running predeploy script.
i  functions: ensuring necessary APIs are enabled...
✔  functions: all necessary APIs are enabled
i  functions: preparing functions directory for uploading...

Error: Error occurred while parsing your function triggers.

【问题讨论】：

标签： firebase google-cloud-functions firebase-admin firebase-cli

【解决方案1】：

根据您的解释，由于您收到的错误是缺少凭据，我真的怀疑它与函数本身有关。

我可以建议两件事：

首先：更新firebase-admin包，

第二：设置服务账号和GOOGLE_APPLICATION_CREDENTIALS变量，并在this procedure之后显式初始化SDK
