Firebase函数无法部署:SyntaxError:意外的令牌函数 [英] Firebase functions cannot deploy : SyntaxError: Unexpected token function

问题描述

我正在尝试将功能部署到Firebase，并且在部署过程中出现错误

I am trying to deploy a function to firebase and I get an error during deployment

错误:功能未正确部署.

Error: Functions did not deploy properly.

可以将其与异步功能链接吗?

Could it be linked with the async function ?

实际行为 功能部署时出现错误，cli向我显示以下消息:

Actual behavior Functions get deployed with errors, the cli shows me the following message:
