Uncaught Error: No router instance found.
You should only use "next/router" inside the client side of your app.

Hey thanks.
But I can't run the error.

It's kind a great, if we can have a isolated issue for this case. Then it saves everyone's time and we could have a look at more issues.

I've tried to deploy this to now but having trouble with the installation there. But I've noticed when running next build && NODE_ENV=production next start locally the router seems to behave as intended.

that is weird, I got the same issue too. How can we make it work running dev?

[noway]

Instead of running global next which doesn't pick up localy installed npm packages run npm run dev

fixed for me

I ran through the same error while npm linking a package which had next as a dependency. Turns out the error goes away if the package is not linked. @noway's answer brought me to that direction!

Running into this too, related to https://github.com/zeit/next.js/issues/3108 linking packages. Will try not using npm link.

Ran into this not having used getInitialProps on the page where the component was mounted.
