Hello Jmf, thank you for asking. I understand what you mean, that the Install button is not there.
There are a few things i can suggest to help you. Have you tried looking in the top-right menu or go to Settings in the bottom-left? Maybe you can upgrade if the version below 0.187.0.
If you’re using Docker, enable community packages (self-hosted). You can add this in your .env or Docker environment block
N8N_COMMUNITY_PACKAGES_ENABLED=true
Then restart n8n.
If the problem persists, perform a manual installation,
From your n8n installation folder:
cd ~/.n8n
npm install n8n-nodes-puppeteer
Then restart n8n, and you should see the Puppeteer node in the panel.
Thats probably all i can suggest. I hope the problem gets resolved yaa.
