Did you install it from the node-red folder? Normally that is `~/.node-red`.

What did the install log say when you installed it? When you go into the node-modules folder within your nodered folder is it there? Dont install it globally.

looks good, when you start nodered with `node-red-start` or when you look in /var/log/syslog after a `sudo systemctl restart nodered` do you see any errors there in the nodered start up?

This seems to be an error, not? How did you install epoll on windows?

What happens if you run `npm rebuild` inside `~/.node-red` folder?

At least it attempted to build something and epoll was mentioned there. I couldn't spot an error from the output either (as it was not properly formatted). Does it work now?

It looks a bit like that was not the full output. There was nothing indicating the end of build.

Show us the package.json from your node. Does it include the node-red section?
