Firebase 函数 onCall，响应：警告，缺少 FIREBASE_CONFIG 环境变量。初始化 firebase-admin 将失败

Question

我尝试从本地项目调用我的测试函数。

但是每次我打电话时，我都会收到 401 错误。我不知道这里有什么麻烦，在前端我有带 api 密钥的 init 应用程序，在我有 firebase 功能admin.credential.applicationDefault()；我试图通过admin.credential.cer(apiConfig)，但这无济于事。

我也有环境变量GOOGLE_APPLICATION_CREDENTIALS，带有我的配置路径。

依赖关系

    "firebase-admin": "~7.0.0",
    "firebase-functions": "^2.2.0",
    "firebase-functions-test": "^0.1.6",

我的功能

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';

admin.initializeApp({
    credential: admin.credential.applicationDefault(),
    databaseURL: "https://plan-list.firebaseio.com"
});

exports.createInviteUser = functions.https.onCall( (data, context)=> {

  return data;

});

前端功能请求

 createInviteUser(email: string) {
        let inviteFunction = firebase.functions().httpsCallable('createInviteUser');

        inviteFunction(email)
            .then((result) => {
            // Read result of the Cloud Function.
           console.log(result);
        })
            .catch(err=>{
                console.log(err)
            });
    }

另外，我怎么看我有所有必需的标题

这里从控制台记录

使用 Node v10 部署函数时会发生此错误。它是由firebase-functions 中的错误引起的。有一个修复程序，但尚未发布。在此之前，请通过更改package.json文件降级到 Node v8 ：

  "engines": {
    "node": "8"
  }
