Firebase 部署错误 - 找不到模块 'firebase'

Question

我正在尝试部署从 db 事件触发的 Google Cloud 函数触发器，但是当我运行 firebase deploy 时功能未正确部署，我收到一条错误消息 Error: Cannot find module firebase
当我第一次创建项目时，我可以毫无问题地部署功能。自从我上次部署任何东西以来已经有几天了，但现在我的所有功能都遇到了这个问题(不仅仅是我的触发功能)

我的功能:

exports.deleteNotificationOnUnlike = functions
    .region("us-central1")
    .firestore.document("likes/{id}")
    .onDelete((snapshot) => {
        return db
            .doc(`/notifications/${snapshot.id}`)
            .delete()
            .catch((err) => console.error(err));
    });

包.json

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "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": {
    "busboy": "^0.3.1",
    "firebase-admin": "^8.0.0",
    "firebase-functions": "^3.1.0"
  },
  "devDependencies": {
    "firebase-functions-test": "^0.1.6"
  },
  "private": true
}

期望功能成功部署但收到此错误:

来自 firebase 的错误消息:

Did you list all required modules in the package.json dependencies?

我看过一些帖子，人们缺少一些模块并需要运行 npm i XXX在functions文件夹中，但我没有看到任何实例说找不到firebase模块，而且我不确定上次成功部署发生了什么变化，或者我可能缺少什么模块。

确保从函数目录安装包，而不是项目目录。当我在项目目录中意外安装软件包时，我多次收到此错误，它在本地运行良好，但在部署期间创建了此类错误。因此，转到功能并从那里安装

cd functions
npm install [your package]

然后它通常工作正常
