Firebase-tools: firebase deploy --only functions without node_modules

[fly1ted]

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?

i  runtimeconfig: ensuring necessary APIs are enabled...
+  runtimeconfig: all necessary APIs are enabled

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

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

The Firebase CLI executes your code locally in order to parse the triggers, so you must have node_modules locally in order to deploy. However, when we pack up the functions directory to upload we ignore node_modules so whether it's there or not will not impact deploy time.

what is the solution?

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.

image: node:6

before_script:
  - npm install -g firebase-tools
  - npm install -g bower
  - npm install -g polymer-cli

cache:
  paths:
    - node_modules/
    - functions/node_modules/
    - bower_components/

deploy_to_firebase:
  stage: deploy
  environment: Production
  only:
    - master
  script:
    # cd to the functions directory and `npm install` so firebase-functions is installed
    - cd functions && npm install && cd -
    - bower install --allow-root
    - polymer build
    - firebase use --token $FIREBASE_DEPLOY_KEY
    - firebase deploy -m "Pipeline $CI_PIPELINE_ID, build $CI_BUILD_ID" --non-interactive --token $FIREBASE_DEPLOY_KEY

laurenzlong solution is correct, but watch out!

You'll have more than one package.json in your project. I missed her point about the functions directory the first time I read it.

run the following inside of your functions directory:

I messed up and ran npm install googleapis --save in the Project Directory. Be sure to run npm install in the functions directory::

project\functions

Would you like to help me ?
I am also facing the same problem and I run this npm install in functions directory but this response!

[laurenzlong]

@badarshahzad It looks like you're running into npm permission issues (this is not a problem with firebase-tools, but your local setup). https://docs.npmjs.com/getting-started/fixing-npm-permissions will hopefully help you fix it.

[badarshahzad]

thank you @laurenzlong the problem is solved.

Issue: yesterday night the problem was the android studio projects in root directory and I created the firbase-funcitons directory along with my android project. I just create new dir on desktop and repeat all steps and it starts working. :100:

So sometimes this happens if you have your cloud functions in one dir, and the rest of your app in another. Make sure to go into /functions and run npm i as your base npm install may have work but GCF has it's own. Not sure if thats helpful

Hi All,

I saw the same Error Message in deploying. I tried the above suggestions (you can see the recording of these below), this Error Message appeared several times.

@eGlobeBizCom I can't tell what's going on here and it seems quite specific to your set up, can you file a support ticket and provide as much details as you can about what's in your package.json and what's in your functions/node_modules

Hi I know this is not the right place, but we got an issue as in the link below suddenly today.
@google-cloud/firestore node library refers a specific version of nanomatch which has a bug.
Firebase functions for firestore stops working due to this from today's lunch time (in JST). As you mentioned above, updating node modules in our local project doesn't fix the issues, since our local node_modules are not the ones actually used after deploy. Can you fix the issue?
