FIrebase deploy error: Cannot find module 'firebase-admin'

Question

I recently started getting the error below when trying to deploy to Firebase (after having done so successfully in the past). I'm not sure what might have changed for this to start occurring. If I run firebase serve to serve on the localhost, everything works fine. My package.json and requires from index.js are also below.

i  deploying functions, hosting
i  functions: ensuring necessary APIs are enabled...
i  runtimeconfig: ensuring 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.

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
}

From 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

They have an active service disruption. Follow this for a workaround: https://status.firebase.google.com/incident/Functions/17024

Run the following commands inside the functions repository:

npm install --save-exact [email protected] npm install --save-exact [email protected]

Then try deploying functions again:

firebase deploy --only functions

If npm doesn't work, you can try yarn which worked for us:

yarn add [email protected] --exact yarn add [email protected] --exact

Answer 2

So the issue is that package.json inside Functions folder is different from package.json in your project directory. yes, you have 2 of this file!

So if you want to deploy, (deploy Functions), run npm install express or install other dependencies inside Function folder and you will be able to deploy with no error.
