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，并遇到以下错误：

​

"i  Starting emulators: ["functions","hosting"]

我已经完成了所有的NPM安装，但不可能...几个小时前，它工作了，最近停止了工作。我的合作伙伴正在运行相同的代码，这对他来说很有效。

有人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 here上打开。

因此，解决办法是将您的系统降级到node8，因为它是您想要使用的引擎。
