无法访问 Firebase Functions 项目中的全局方法

Question

我希望我的 Firebase 管理项目中的多个函数具有相同的方法例如：“生成随机字母数字字符串”。因此，为了避免使用样板代码，我在该文件夹中创建了一个 Utils 文件夹和一个 utilityFunctions.ts 文件。该文件仅包含一个生成字母数字字符串的导出函数。我已使用 import 语句将该文件导入我的函数文件之一。

这是我的文件，其中包含预期的全局方法：src/Utils/utilityFunctions.ts

export const theRandomDocId = function randomDocumentId(length: number): 
String {
// the code to generate a random string
}

这是我的一个函数文件：src/Compliment/addNewCompliment.ts

import * as functions from 'firebase-functions'
const admin = require('firebase-admin')
//This import statement below for the utilityFunctions file
import utilityFunctions = require('../Utils/utilityFunctions')

export const addTheNewCompliment = functions.region('asia-east2').https.onCall((complimentData, 
context) => {

//generate random 11 alphanumeric ComplimentId converted to String
const randomComplimentId = utilityFunctions.theRandomDocId(28)

//There is a lot more code in this file but since its not relevant to the 
//problem, I have excluded it.

}

这是 vs 代码显示的错误：

!  functions[addNewCompliment(asia-east2)]: Deployment error.
Function failed on loading user code. Error message: Code in file lib/index.js can't be loaded.
Did you list all required modules in the package.json dependencies?

我也尝试过在没有导出变量的情况下声明该方法，并在没有导入语句的情况下从我的 addNewCompliment.ts 文件中访问该方法，代码编译但是当它被触发时，Firebase 函数日志会引发错误：

Unhandled error ReferenceError: randomDocumentId is not defined

这是我的 package.json 文件

您的Utils 目录是否在您的functions 目录中？部署时，只会将functions 目录发送到服务器，因此不会上传不在该目录中的任何内容。如果这不是问题，请确保您的大小写匹配，因为 Cloud Functions 后端具有区分大小写的文件系统。
