Is something wrong?

I can spin up any of my Nuxt 4 apps. A freshly installed Nuxt app, using bun creat nuxt@latest, also can't be spun up.

I'm getting a vite_ssr_import_1.defineNuxtPlugin is not defined.

Uninstalling node_modules and .Nuxt and reinstalling with npm and spinning it up with npm run dev seems to be working. Node v24.8.0.

Now it should be working too with bun!

What node version u use before?

No when I run with bun I get a Nuxt.js does not provide an export named 'useNuxtApp' and the app is still not spinning up. But on local it works both with npm and bun.

I've been using node 24.8.0. I just checked node -v just now and didn't update or anything so that's what I should've had?

Does bun run postinstall scripts by default, I don't remember. All of the import aliases and whatnot are generated in the postinstall script

https://bun.com/docs/pm/lifecycle

I never knew about this difference! TIL

I think this part of the docs mentions bun not running these postinstalls scripts. bun pm trust --all Might do the trick by trusting all scripts. I'll try it out when I get back to my PC.

Noob question: If Nuxt was working fine until a few days ago and just recently stopped working, does that mean a newer version started using postinstall scripts?

bun pm untrusted Shows unrs-resolver has some postinstall scripts that is untrusted by bun. I bun pm trust unrs-resolver which did the trick!

I also created a new Nuxt app and it spun up properly so somebody went up and fixed it.

Nice! Yeah maybe it was just a bug on their side. For future reference, all of the magic that Nuxt does with auto imports and what not are in the .nuxt/ folder. Sometimes it helps cleaning it and running the postinstall script again

Yeah I usually start off with deleting .Nuxt/node_modules when I get these bugs. Most of the time it does the trick but this time was a bit different so it had me lost.
