vue3 setup props泛型外部引入报错

Question

vue3 setup defineProps的泛型从外部引入报错

这样引入报错 Syntax Error: TypeError: Cannot read property 'content' of null

<script lang="ts" setup>
import type { IProps } from "./type"
import { withDefaults, defineProps } from "vue"
// interface IProps {
//   title: string

//   activeBgc?: string
//   activeColor?: string
// }
const props = defineProps<IProps>()
</script>

这样正常

<script lang="ts" setup>
// import type { IProps } from "./type"
import { withDefaults, defineProps } from "vue"
interface IProps {
  title: string

  activeBgc?: string
  activeColor?: string
}
const props = defineProps<IProps>()
</script>
