Error shows 'cannot find module firebase-functions' when deploying a firebase project

Question

When I am trying to deploy a firebase project it shows an error message 'cannot find module firebase-functions' in npm console.The steps(node commands) I have done are:

1. npm install -g firebase-tools
2. firebase login
3. firebase init

and finally where I stucked is
4. firebase deploy

Please help me.

Answer 1

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

npm install firebase-functions

Answer 2

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.

Answer 3

you should install node_modules in the functions directory in your project

cd functions
npm install 

then run firebase deploy

Answer 4

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
