Tanstack router SSR, unable to import @tanstack/react-router-server package as guide indicates

[tonymtz]

Hello!

I'm following this guide: https://tanstack.com/router/latest/docs/framework/react/guide/ssr; the non-streaming SSR part.

As the guide states, I should use StartClient from @tanstack/react-router-server. When I'm importing this, my code doesn't recognize the module:

TS2307: Cannot find module @tanstack/react-router-server or its corresponding type declarations.

The sample applies if I try @tanstack/react-router-server/server or @tanstack/react-router-server/client as other parts of the same guide indicate.

I tried installing it as an npm module: npm i @tanstack/react-router-server, but the problem persists.

I've been trying (for months now) to add this library to our app. Unfortunately, the guides don't seem to be up to date or are not clear enough.

I cannot pass from this import error:
