firebase deploy --only functions without node_modules

From the docs I concluded that it’s not necessary to have local pckgs in node_modules installed for GCS to operate: it should install them in the instance based on package.json. So, I deleted node_modules coz it seemed that it uploads and takes some time to do that. However I get an err. Anyone else has this?

Error: Error parsing triggers: Cannot find module 'firebase-functions'

Try running "npm install" in your functions directory before deploying.

Hi @jjhesk , run the following inside of your functions directory:

npm install
firebase deploy

I ran into this and struggled with it for a bit so just to add some help to others that might run across this and not see the obvious answer.

If you’re using some kind of automated pipeline then you will likely need to specifically add the cd functions && npm install && cd - to the runner. Below is an example .gitlab-ci.yml that I use for for a gitlab polymer project.

I think I got hung up on this because I didn’t have to do that step locally when I first setup the project. Likely firebase init just did it for me.
