Cannot find module 'firebase-admin' when trying to deploy Firebase functions

Question

I have deployed the three functions successfully for a couple of month, and now it suddenly started trippin' on me. I haven't changed the node, npm or firebase cli versions for a while. I upgraded the npm packages within the functions directory as a desperation to fix this, but no luck. Why is this happening? Repo (hoverboard-v2 branch): https://github.com/gdgfresno/valleydevfest2017/tree/hoverboard-v2/functions

Ubuntu 17.04, console deployment

npm --version
5.5.1
node --version
v8.1.0
firebase --version
3.13.1

Here is the error:

Deployment failure:

Function load error: Code in file index.js can't be loaded.
Did you list all required modules in the package.json dependencies?

index.js:

'use strict';

const functions = require('firebase-functions');
const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

exports.sendGeneralNotification = require('./notifications');
exports.scheduleNotifications = require('./schedule-notifications');
exports.saveUserData = require('./users');

Answer 1

Same issue here. It is a firebase problem.

There is disruption in firebase cloud service since yesterday.

problem description: https://status.firebase.google.com/incident/Functions/17024

problem solution:

Run the following commands inside the functions repository:

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

Then try deploying functions again:

firebase deploy --only functions

I hope this helps :)

Answer 2

I have sorted it out using previous versions:

npm install --save-exact firebase-functions@0.6.3

npm install --save-exact firebase-admin@5.2.1

At least until it would be resolved
