Firebase 管理员无法读取未定义的属性“证书”

Question

我用 firebase admin 编写 hapi 后端 api。我找不到此错误的修复方法。

TypeError: Cannot read property 'cert' of undefined at ModuleJob.run (internal/modules/esm/module_job.js:109:37) at async Loader.import (internal/modules/esm/loader.js:133:24)

代码：

import * as admin from 'firebase-admin';
import serviceAccount from './resources/serviceAccount.js'
let storageBucket = process.env.NODE_ENV === 'production' ? '' : 'gs://myapp-dev.appspot.com'

let app = admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: process.env.NODE_ENV === 'production' ? "https://myapp.firebaseio.com" : "https://jointcreative1-dev.firebaseio.com"
});

包json：

 {
  "name": "backend",
  "version": "1.0.0",
  "description": "Hapi/joi backend server",
  "type": "module",
  "main": "server.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node server.js"
  },
  "author": "XXX",
  "license": "MIT",
  "dependencies": {
    "@hapi/hapi": "^19.1.1",
    "firebase": "^7.14.6",
    "firebase-admin": "^8.12.1",
    "firebase-tools": "^8.4.1",
    "google-auth-library": "^0.12.0",
    "hapi-auth-jwt2": "^10.1.0"
  }
}

我在 sapper 中使用它，一切正常，但由于某种原因进入 hapi 却破坏了它。

这个问题在几年前就已经得到解决，但此后已经发布了多个主要版本。

Answer 1

正如 package.json 中写的那样"type":" module"

看起来您正在使用 ES 模块，因此请尝试以下操作：

import admin from 'firebase-admin';

Answer 2

你尝试过这个吗？

var serviceAccount = require('./resources/serviceAccount.js');
let app = admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  ...
});
