📚 Description

We are overriding shouldExternalize (PR: #6153) of vite-node, and use mlly resolver to directly resolve paths. Issue with nuxt/nuxt#14952 happens because directly setting URL to the directory of rootDir, causes resolving from parent node_modules and finally different resolved vue version. (Correct way is setting rootDir + '/_node_modules' or rootDir + /index.mjs)

This PR resolves issue by respecting modulesDir for resolving vue and other dependencies. In the future we might come of with better implementation to actually reuse same vite resolution. I didn't use return id on external branch (while it works!) until getting confirmation from @antfu. Vite-node's default external handler however does this. src

Also worth to mention that isExternal('vue') resolves to null as it is unable to determine external status.

@antfu Shall we do this to be same as vite-node? Would it diretly require vue or let vite resolve to fullpath?

Suggested change

	returnresolveModule(result.id,{url: ctx.nuxt.options.modulesDir})
	returnid

[antfu]

The id passed here should already be resolved by Vite. So yes I think we could directly do this.

Thanks for checking. FYI, it is not always resolved. You can reproduce it only with an external repository by putting a debugger. vue for instance is directly passed to shouldExternalize.

Merging as hotfix.
