Node.js Firebase云功能节点8-“；错误：Can'；“找不到环境配置”；远程部署时

我正在用节点8的typescript编写firebase云函数。为了从云功能访问firebase存储桶，我以以下方式在

index.ts

中初始化了我的CFs，以便在prod和dev firebase项目之间切换：

import * as admin from 'firebase-admin'
import * as geofunctions from 'geofirestore'

if(!process.env.FIREBASE_CONFIG){
    throw Error("Can't find env config")
}

const adminConfig = JSON.parse(process.env.FIREBASE_CONFIG)
const projectId = adminConfig.projectId

const certPath = projectId + '.json'
const bucketUrl = projectId + '.appspot.com'

admin.initializeApp({
    credential: admin.credential.cert(certPath),
    storageBucket: bucketUrl
});

这符合：

这在本地运行时效果良好，例如：

firebase-p dev-service

但是，当我使用

firebase deploy-p dev--only functions

远程部署时，所有函数都会失败，并出现以下错误：

⚠  functions[<<MY FUNCTION NAME>>(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?

你知道我做错了什么吗
