Cannot find module 'next' or its corresponding type declarations, though next is installed

[JoshuaKGoldberg]

I'm a big fan of shiki-twoslash, thanks for making it! But I'm not able to get it to recognize types from the next package. See around https://learning-typescript-git-the-satisfies-operator-joshuakgoldberg.vercel.app/articles/the-satisfies-operator#nextjs-and-satisfies:

Shouldn't shiki-twoslash be detecting the Next types from node_modules/next? I also couldn't find explicit docs on type detection anywhere, other than #134 referencing that it exists normally.

It should! I'm probably not going to be at a place where I can provide much debugging help, but it's likely that either the next types do something unique (quite possible) or I hadn't accounted for or the folder structure

The interesting code is in

and

...huh. It went away on its own. I think this isn't a case of me forgetting to install modules, because it happened in CI. But 🤷

Sorry for the noise either way. Closing this for now, but if someone else sees it too, please speak up!
