Cloud Functions 部署失败："Function failed on loading user code. Error message: Code in file lib/index.js can't be loaded."

Question

我将我的 firebase-functions 模块升级到了 3.0.1。现在，当我部署 Cloud Functions 时，我收到警告消息：

⚠ functions: Deploying functions to Node 6 runtime, which is deprecated. Node 8 is available and is the recommended runtime.

然后，部署失败：

Function failed on loading user code. Error message: Code in file lib/index.js can't be loaded.
Is there a syntax error in your code?
Detailed stack trace: /user_code/node_modules/firebase-functions/lib/providers/https.js:282
    const func = async (req, res) => {
                       ^

SyntaxError: Unexpected token (

    at require (internal/module.js:20:19)
    at Object.<anonymous> (/user_code/node_modules/firebase-functions/lib/index.js:39:15)

我该如何解决这个问题？

Answer 1

过去，节点 6 是默认目标运行时。现在，节点 6 已经过期 LTS（长期支持）。在 CLI 版本 6.8.0 中，节点 6 已被弃用，我们鼓励您以节点 8 为目标进行部署。现在，从 firebase-functions@3.0.0 开始，节点 6 支持已完全删除，您必须在 package.json:

中明确定位节点 8

{
  // other configurations here…
  "dependencies": {
  },
  // Add an “engines” child to choose a node version, here it’s node 8.
  "engines": {
    "node": "8"
  }
}

此版本中的另一个相关更改是对 firebase-admin 8.x 的依赖，它也放弃了对节点 6 的支持。

错误消息本身表明无法识别关键字 async，节点 6 不支持该关键字。
