node.js - 运行Firebase服务时Firebase找不到 'firebase-admin'模块

Question

我在本地运行我的应用程序，但遇到此错误:

"i  Starting emulators: ["functions","hosting"]
⚠  Your requested "node" version "8" doesn't match your global version "12"
✔  functions: Emulator started at http://localhost:5001
i  hosting: Serving hosting files from: public
✔  hosting: Local server: http://localhost:5000
✔  hosting: Emulator started at http://localhost:5000

我已经完成了所有 NPM 安装，但没办法...几个小时前它还可以工作，最近停止工作了。我的合作伙伴正在运行相同的代码，并且它对他有用。

有谁知道问题出在哪里吗？

这是我的 package.json:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "lint": "eslint .",
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "8"
  },
  "dependencies": {
    "express": "^4.17.1",
    "firebase-admin": "*",
    "firebase-functions": "^3.3.0"
  },
  "devDependencies": {
    "eslint": "^5.12.0",
    "eslint-plugin-promise": "^4.0.1",
    "firebase-functions-test": "^0.1.6"
  },
  "private": true
}

谢谢!

这是一个已知问题，该问题已在 github 上打开 here

因此，解决方法是将系统降级到 Node8，因为它是您要使用的引擎。
