node.js - 尝试部署 Firebase Functions 教程时出现语法解析错误

Question

我正在关注the Cloud Functions tutorial以了解如何使用 Firebase 函数。一切都很顺利，直到 the stage I needed to deploy to the cloud - 由于某种原因，我遇到了语法异常!看来异常是由 lambda 函数引起的:

$ firebase deploy --only functions

=== Deploying to 'my-project-87547'...

i  deploying functions
Running command: npm --prefix "$RESOURCE_DIR" run lint

> functions@ lint E:\Users\Emmet\Documents\firebase_tutorial\functions
> eslint .

真正奇怪的是我逐字使用 index.js provided in the tutorial itself ，并且它在 Firebase 本地模拟器套件中也按预期成功通过。

作为引用，我正在 Windows 10 PC 上的 Git Bash 终端(使用管理员)运行所有命令。 我的 npm 版本是 6.14.11，NodeJS 版本是 v14.16.0。

我知道其他人也遇到过类似的问题，但我还没有看到有人通过教程脚本本身解决这个问题。提前致谢!

Answer 1

我也有过类似的经历。最终对我有用的是改变 "lint": "eslint .", 到 "lint": "eslint", 在 package.json 内。

我怀疑这是由于在 Windows 计算机上运行该项目所致。
