Firebase函数：函数未定义
[英]Firebase Functions: functions is not defined
问题描述
In index.js, I have: 
在index.js中，我有：
exports.makeUppercase = functions.database.ref('/messages/{pushId}/original').onCreate((snapshot, context) => {
// Grab the current value of what was written to the Realtime Database.
const original = snapshot.val();
console.log('Uppercasing', context.params.pushId, original);
const uppercase = original.toUpperCase();
// You must return a Promise when performing asynchronous tasks inside a Functions such as
// writing to the Firebase Realtime Database.
// Setting an "uppercase" sibling in the Realtime Database returns a Promise.
return snapshot.ref.parent.child('uppercase').set(uppercase);
});
I literally copy-pasted the code from: https://firebase.google.com/docs/functions/get-started 我从字面上复制粘贴了以下代码： https ： //firebase.google.com/docs/functions/get-started
Somehow, when I deploy using 不知何故，当我使用
firebase deploy --only functions
I get: 我得到：
Error: Error occurred while parsing your function triggers.
What's going on, and how do I fix it? 怎么回事，如何解决？

As the setup documentation explains, you need to import required modules and initialize the app: 如安装文档所述 ，您需要导入所需的模块并初始化应用程序：
// The Cloud Functions for Firebase SDK to create Cloud Functions and setup triggers.
const functions = require('firebase-functions');
// The Firebase Admin SDK to access the Firebase Realtime Database.
const admin = require('firebase-admin');
admin.initializeApp();
