`Cannot find name defineProps` ts error

In a vue2 + vite + unplugin-vue2-script-setup project i have a ts error (not eslint) on build that Cannot find name defineProps/defineEmits

Here’s project’s tsconfig https://github.com/jacekkarczmarczyk/rachunek/blob/master/tsconfig.json and example usage of defineProps https://github.com/jacekkarczmarczyk/rachunek/blob/master/src/components/BillForm/BillForm.vue#L163 (that’s not a minimal repro, but I guess just the settings files are imporant, if you want a minimal repro though let me know)

To reproduce the issue run yarn build

Error can be supressed with // @ts-ignore but that doesn’t sound like a valid solution. Another option is to add .d.ts files with defineProps declaration but I think that should be rather provided by the lib (or maybe it is but can’t find anything)

hm what is https://github.com/johnsoncodehk/volar then? nvm, I see now still i think that putting information about dependency in the IDE section is misleading, writing about Vetur, Volar and VS Code in one sentence may make people think that it’s about using Volar extension in VS Code

It happens to me because I didn’t give it npm install, but then you have to disabled Vetur if you have it installed
