Cannot import Vue 3 types from @vue/runtime-dom. If you are using Vue 2, you may need to install @vue/runtime-dom in additionally.

Have you install node_modules? If yes please show your package.json.

I tried your package.json and tsconfig.json with yarn and pnpm but can't reproduce, can you try this template? If works please compare different.

[ercmage]

Hi thanks, yeah it's working. I also try to create fresh vue-cli project, and volar works just fine there, so i moved all my source to the new vue project and it works. Don't know what caused it before, very strange.

[TheDutchCoder]

I still get this every time I start VSCode. It doesn't seem to affect anything though.

I wonder if it's due to me opening a monorepo where Vue is not installed in the root, but in one of the sub packages.

[johnsoncodehk]

@TheDutchCoder some features like html elements type-checking, GlobalComponents interface... may not working in some *.vue file.

If you can't resolve this warning, please provide a minimal reproduce.

[TheDutchCoder]

I have a feeling it has something to do with import { defineComponent, ref, Ref } from 'vue' Auto-import actually resolves to '@vue/runtime-dom', not 'vue', so I'm wondering if there's some sort of module mapping that's off?

To clarify, if I start typing export default defineCom, the auto-import will add import { defineComponent } from '@vue/runtime-dom', instead of import { defineComponent } from 'vue' (which is what I would expect).

I think this is volar bug, because access to @vue/runtime-dom is not a security behavior.

[johnsoncodehk]

@tjx666 this is TS problem, see https://github.com/tjx666/electron-vue-vite-boilerplate/pull/1.
