ts error: cannot find name "ref"

[seho-dev]

When I use unplugin-auto-import, a plug-in that automatically imports functions, I just write a ref and my program will report an error. How can vue-tsc solve it?

<script lang="ts" setup>
const a = ref<number>(1)
</script>

I think there already has workaround, see https://github.com/antfu/unplugin-auto-import/issues?q=cannot+find+name.
