I ran into this same issue scratching my head since I could clearly see firebase-functions in my package.json and it was definitely installed.

Then I remembered that I'm deploying (inherently production), and firebase-functions was in my devDependencies section of package.json instead of dependencies.

In case someone runs into this same issue, double check that firebase-functions is in dependencies as it won't be included in the resulting bundle or deployment otherwise. In my case, I needed to explicitly add it to my functions/package.json.

E.g. -> Move a module from devDependencies to dependencies in npm package.json

I'm using @nrwl/nx monorepo and moved /functions to /apps and all my node pages are in the root project folder. What worked for me is to replace the double quotes with single quotes

import * as functions from "firebase-functions";

to

import * as functions from 'firebase-functions';

This may happen if you have requires with wrong cases!

The firebase function file system seems to be case sensitive.

So if you do

const { myStuff } = require('./mystuff');

but the file is actually named myStuff.js, it may very well work locally, but fails on build

It's simple! If it says can't find module firebase-functions then install them.

npm install firebase-functions

you should install node_modules in the functions directory in your project 

cd functions
npm install

then run firebase deploy

Could be that you didn't follow the instructions provided when running "firebase init". You should press space and then enter in order to select the option you want - possibly that's why there was no functions folder.
