FIrebase 部署错误：找不到模块“firebase-admin”

Question

我最近在尝试部署到 Firebase 时开始收到以下错误（在过去成功部署之后）。我不确定发生这种情况可能会发生什么变化。如果我运行 firebase serve 在本地主机上服务，一切正常。我的 package.json 和 index.js 的要求也在下面。

i  deploying functions, hosting

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

Functions deploy had errors. To continue deploying other features (such as datab
ase), run:
firebase deploy --except functions

Error: Functions did not deploy properly.

package.json:

{
"name": "functions",
"description": "Cloud Functions for Firebase",
"dependencies": {
"@google-cloud/vision": "^0.12.0",
"async": "^2.5.0",
"consolidate": "^0.14.5",
"express": "^4.15.4",
"firebase-admin": "^5.4.0",
"firebase-functions": "^0.5.7",
"handlebars": "^4.0.10",
"jquery": "^3.2.1",
"js-levenshtein": "^1.1.3",
"json-query": "^2.2.2"
},
"private": true
}

来自 index.js：

const functions = require('firebase-functions');
const firebase = require('firebase-admin');
const express = require('express');
const engines = require('consolidate');
const Vision = require('@google-cloud/vision');
const levenshtein = require('js-levenshtein');
const restName = require('./restName');
const parser = require('./parser');
const jsonQuery = require('json-query')

const firebaseApp = firebase.initializeApp(
functions.config().firebase
);

Answer 1

他们有一个活跃的服务中断。按照这个解决方法：https://status.firebase.google.com/incident/Functions/17024

在函数存储库中运行以下命令：

npm install --save-exact firebase-functions@0.7.0 npm install --save-exact firebase-admin@5.4.0

然后再次尝试部署函数：

firebase deploy --only functions

如果 npm 不起作用，您可以尝试对我们有用的 yarn：

yarn add firebase-functions@0.7.0 --exact yarn add firebase-admin@5.4.0 --exact

Answer 2

更新文件夹函数中的 package.json 文件并查看依赖关系 从 firebase-admin 中删除符号 ~ 并从 firebase-functions 中删除 ^ 它应该是这样的：

"dependencies": {
  "firebase-admin": "5.4.0",
  "firebase-functions": "0.7.0"
}

在命令行类型中

npm 安装

然后尝试再次部署。

Answer 3

我也遇到了同样的错误。我通过在 nodejs 中安装不同版本来修复该错误。我卸载了我的新版本并安装了 Node v7.8.0。然后它工作正常:)

Answer 4

我去了函数目录并运行yarn（或者npm install，如果你是老派的话）。然后回到我的项目目录，再次运行firebase deploy。

Answer 5

所以问题是 Functions 文件夹中的 package.json 与您项目目录中的 package.json 不同。是的，你有 2 个这个文件！

所以如果你想部署，（部署 Functions），运行 npm install express 或在 Function 文件夹中安装其他依赖项，你将能够毫无错误地部署。

Answer 6

尝试安装：npm i -g firebase-tools@6.8.0

这解决了我的问题。

Answer 7

运行以下命令

npm i firebase-admin
