尝试在 node.js 中使用谷歌云函数时，admin.firestore 不是一个函数 [英] admin.firestore is not a function when trying to use google cloud functions with node.js

问题描述

这是 node.js index.js 文件的标题:

This is the header of the node.js index.js file:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
var db = admin.firestore();

这是用于监听 firestore 变化的 node.js 函数:

This is the node.js function to listen to firestore changes:

exports.myFoo = functions.firestore
  .document('foo/{bar}')
  .onWrite(event => {
    // do stuff
}

这是在 package.json 文件中:

This is in the package.json file:

  "dependencies": {
    "firebase-admin": "^5-.4.2",
    "firebase-functions": "^0.7.1",
    "firestore": "^1.1.6"
  },

当我尝试进行firebase 部署"时命令这是我得到的错误:

When I try to do a "firebase deploy" command this is the error I am getting:

错误:解析函数触发器时出错.
类型错误:admin.firestore 不是函数

Error: Error occurred while parsing your function triggers.
TypeError: admin.firestore is not a function

推荐答案

我能够重现错误并强力解决方案.我对 npm 知之甚少，无法完整解释此解决方案为何有效.

I was able to reproduce the error and brute-force a solution. I don't know much about npm and can't offer a complete explanation of why this solution worked.

我原来的 package.json 包含:

  "dependencies": {
    ...
    "firebase-admin": "^4.2.1",
    "firebase-functions": "^0.7.1",
    ...
  },

作为在文档中推荐，我在功能文件夹:

As recommended in the documentation, I ran these two commands in the functions folder:

npm install -g firebase-tools
npm install firebase-functions@latest --save

我也试过:

npm install --save firebase-admin
npm upgrade

我反复收到这些错误消息:

I repeatedly received these error messages:

+-- UNMET PEER DEPENDENCY firebase-admin@4.2.1
npm WARN firebase-functions@0.7.1 requires a peer of firebase-admin@~5.4.2 but none was installed.

我认为 firebase-admin 需要更新，但无法实现.所以我编辑了依赖文件以删除这一行:

I figured firebase-admin needed to be updated but couldn't make it happen. So I edited the dependencies file to delete this line:

"firebase-admin": "^4.2.1"

然后再次运行 npm install --save firebase-admin.这样，package.json 包含版本 "firebase-admin": "^5.4.2" 和 var db = admin.firestore(); 编译没有错误.

then ran npm install --save firebase-admin again. With that, the package.json contained version "firebase-admin": "^5.4.2" and var db = admin.firestore(); compiled without error.
