Code Node external module not working

[bigfather]

I am having an error in my code node require external module. i need puppeteer. i know there is a puppeteer community node, but its not working from me for some reason. so i am trying to just run it in a code node instead.

Error:

I tried to npm install in the /home/node which you can see in an execute command node npm list. i am not sure what im doing wrong.

Information on your n8n setup

Your setup seems correct at a glance. You may just need to reboot the instance to register the new external packages.

You may have to import the packages a different way if still encountering issues, I have not tested this myself so far.

@ThinkBot hey thanks for your response. i tried to restart my container, and even redeployed also. but it is the same error, cannot fine module puppeteer when running the code node.

one thing though, when i try to restart my container, i needed to install npm puppeteer again. is that normal?

Hey @adomakins, Welcome to the community I am a big fan of this but can you maybe clean it up a little bit to keep it friendly I would also like to add an other option is to use a Dockerfile with FROM n8nio/n8n:latest USER root RUN npm install -g ytdl-core USER node You can then update your Compose file replace image with build like below. n8n: container_name: n8n build: . restart: always ports: - 5678:5678 environment: - NODE_FUNCTIO…
