i know that 

firebase功能：配置：设置someservice.key =“API密钥”someservice.id =“客户端ID”

this command will set environmental variables but what values should I set in environmental variables

I don't understand these lines from firebase documentation: (https://firebase.google.com/docs/functions/config-env)
process.env.GCLOUD_PROJECT: Provides the Firebase project ID
process.env.FIREBASE_CONFIG: Provides the following Firebase project config info:

should i set firebaseConfig details from project settings into environmental variables

Answer 1

FIREBASE_CONFIG和GCLOUD_PROJECT是 Firebase Functions 服务器上的环境变量。未设置它们的原因是因为您尝试在标准节点环境 ( node index.js) 中运行函数代码，而不是在 Firebase 生产服务器上或通过 firebase-tools 包在本地环境中运行它们serve，shell或者emulate在本地运行它们模拟服务器并为您提供正确的配置。

您不必设置这些值 - 只需在 Firebase 模拟器（或 shell）中运行您的函数即可。查看有关如何启动和运行的文档。
