Firebase config variables are not available error with deploying functions

Question

When I am deploying Firebase functions without

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

Firebase logs

Error: The default Firebase app does not exist. Make sure you call initializeApp() before using any of the Firebase services.

But if I add that line I get error on deploy.

>firebase deploy --only functions

Error:

Error: Error occurred while parsing your function triggers. Please ensure you have the latest firebase-functions SDK by running "npm i --save firebase-functions@latest" inside your functions folder.

Error: Firebase config variables are not available. Please use the latest version of the Firebase CLI to deploy this function.

I already did npm i --save firebase-functions@latest which haven't done anything. I am stuck and can't do anything right now because of this... I am down for any reinstalls if they could help just tell me some steps or hints and I would seek for the rest.

NPM and NodeJS versions are:

node -v
v8.9.1
npm -v
5.6.0

Edit. Installation with admin rights:

npm i --save firebase-functions@latest
npm WARN [email protected] requires a peer of firebase-admin@~5.8.1 but none is installed. You must install peer dependencies yourself.

It actually appeared I was on npm version 5.5.1 but even after the update to 5.6.0 I got the exact same error.

Answer 1

There was a breaking change introduced in [email protected] which requires your project to upgrade firebase-functions to the latest version.

However, firebase-functions@latest also requires firebase-admin@latest (at the time of writing this answer [email protected]. Once all packages are upgraded, this problem should be solved.

Another alternative is to downgrade your global firebase-tools to 3.16.0, which lets you use older firebase-functions and firebase-admin packages.

Answer 2

I ran into the same issue in Ubuntu and this is how i solved it

Install firebase using : sudo npm install -g firebase-tools

Also make sure you launch using admin privileges e.g to login

sudo firebase login
