Cannot find module 'puppeteer'

[chalmagean]

Hi,

Trying to deploy a Rails app (using Grover) to Heroku, and I get the following error:

Cannot find module 'puppeteer'. The module was found in '/app/package.json' however, please run 'npm install' from '/app'

I've followed the instructions here: https://github.com/Studiosity/grover#running-on-heroku

Using heroku-20.

What steps have you taken to debug this yourself?

My first suggestion would be to jump on the heroku console and check the contents of /app/node_modules.

You should also be able to check the heroku deploy logs to see that it is installing the puppeteer node modules.

If that folder isn't there and/or you don't see the puppeteer package being installed when you deploy then you've likely missed a step.

Thanks @abrom. I'm closing this for now because I can't reproduce it anymore.

@chalmagean, could you give a bit more information on your setup? I'm experiencing the exact same issue.
