Should be good in 5.0.0-alpha.2

I got error in 5.0.0-aplha.3.

My Babel config

I will take a look at your project. I guess it isn't respecting .babelrc? 🤔

yeah, it works when I renamed it to babel.config.js.

[lmiller1990]

I think the later versions of babel don't support .babelrc. Is this a good enough fix for your project? Or do we need to leave this open?

How to suport <script setup>?

[lmiller1990]

I have not tried this yet. I was hoping it would "just work" - the SFC compiler (should) take care of it, mostly.

What happens when you tried it?

@vue/runtime-core warns [Vue warn]: Property "x" was accessed during render but is not defined on instance. when I run the test script.

Yep, we need to do a check for <script setup>. This should be fairly easy, I will look into it tomorrow or Friday.

<script setup> works. The example needs to be updated a bit because the syntax changed. ``` <script setup lang="ts"> import { defineProps, ref } from 'vue' const props = defineProps({ msg: String }) const count = ref(0) </script>
