FIrebase 部署错误 : Cannot find module 'firebase-admin'

Question

我最近在尝试部署到 Firebase 时开始收到以下错误(在过去成功完成之后)。我不确定发生了什么变化导致这种情况开始发生。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
i  functions: ensuring necessary APIs are enabled...
i  runtimeconfig: ensuring necessary APIs are enabled...
+  runtimeconfig: all necessary APIs are enabled

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.

包.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

我转到函数目录并运行 yarn (或 npm install 如果你是老派)。然后回到我的项目目录并运行firebase deploy再次。
