[Question] it can't work with unplugin-vue2-script-setup

It is a bug.

This lib may have something wrong with unplugin-vue2-script-setup || vue-composition-api.

unplugin-vue2-script-setup && vue-composition-api works fine with this compiler.

See https://github.com/JuniorTour/vue-template-babel-compiler-VueUse-Example

I will look into it and fix it ASAP.

Thanks for your feedback.

Do you use VueCompositionAPI?

I found the unplugin-vue2-script-setup && vue-composition-api works fine with this compiler.

But if you forget to write Vue.use(VueCompositionAPI) , there will be the same undefined error as yours.

So try to add these to your main.ts:

// main.ts || .js
import VueCompositionAPI from '@vue/composition-api'
Vue.use(VueCompositionAPI)

If your issue is still not resolved. Just let me know.

I also made an Example project for vue-template-babel-compiler && VueUse && unplugin-vue2-script-setup && vuejs/composition-api
