I had the same. node v22.9.0 | yarn | "nuxt": "^3.15.0"

yarn add vite typescript helped in my case

"typescript": "^5.7.2" | "vite": "^6.0.7"

@Tristwch not sure you need Vite as explicit dependency, as nuxt 3.15.x adds Vite 6.
But adding typescript as dev dependency fixed it. Thanks for the hint. (:

That is weird.
I had the same issue.
Installing typescript as dev dependencies worked but even without typescript when you try to install via NPM it works!!!
how?!

Some of the recent issues seem to only be present for projects using the yarn package manager, I'm not sure what the core issue/difference is 🤔

Exactly.
I can't guess what's going on to cause these types of issues.
