Cloud Functions Firebase v1.0 不会初始化

随着 Firebase 云功能的最新更新，我在初始化应用程序以及数据库引用时遇到错误。

第一个错误： 以下应该基于 Firebase 函数 v1.0 文档和示例进行工作（https://github.com/firebase/Friendlychat-web/blob/master/cloud-functions/functions/index.js https://github.com/firebase/friendlychat-web/blob/master/cloud-functions/functions/index.js )

const functions = require('firebase-functions'); 
const admin = require('firebase-admin'); 
admin.initializeApp(); //this fails

对于上述代码，我在 firebase 部署时收到以下错误：

Error: Error occurred while parsing your function triggers.

Error: Failed to parse app options file: Error: ENOENT: no such file or directory, open '[object Object]'

    at Object.Module._extensions..js (module.js:654:10)
    at Module.load (module.js:556:32)

如果我传递配置文件，此错误就会解决（但它违反了 firebase 文档）

const functions = require('firebase-functions');
const admin = require('firebase-admin');
var config = {
    apiKey: "<APIKEY>",
    authDomain: "<DOMAIN>",
    databaseURL: "<URL>",
    projectId: "<PROJECTID>",
    storageBucket: "<BUCKET>",
    messagingSenderId: "<ID>"
  };
admin.initializeApp(config);//this works

第二个错误：当我如下进行数据库引用调用时，它失败并给出错误：

const functions = require('firebase-functions');
const admin = require('firebase-admin');

var config = {
    apiKey: "<APIKEY>",
    authDomain: "<DOMAIN>",
    databaseURL: "<URL>",
    projectId: "<PROJECTID>",
    storageBucket: "<BUCKET>",
    messagingSenderId: "<ID>"
  };
  const app = admin.initializeApp(config);

  exports.updateUserProfile = functions.database.ref('/UserProfile/{userid}')
    .onCreate((snapshot, context) => {
        console.log(snapshot.val());
    });

Logs:

您遇到此错误的原因是bug https://github.com/firebase/firebase-tools/issues/722在 firebase CLI 版本 3.18.1 中。 尝试卸载当前版本并安装 3.18.0，这应该可以解决该错误。

npm uninstall -g firebase-tools
npm install -g [email protected] /cdn-cgi/l/email-protection

更新： Firebase CLI 版本 3.18.2 已发布，issue https://github.com/firebase/firebase-tools/releases/tag/v3.18.2现已解决。
