要只允许<div>元素，请使用HTMLDivElement类型。
要允许任何元素，请使用类型HTMLElement。
要允许任何东西，请将type设置为null或undefined（这样linter就不会发出警告）。

下面是一个完整的示例，使用TypeScript和Nuxt与SSR。
通过评论添加了更多上下文。

<script lang="ts">
import { defineComponent, PropType, toRef, watchPostEffect } from '@nuxtjs/composition-api'

export default defineComponent({
  props: {
    element: {
      // When using Nuxt SSR, use this otherwise you get error
      // This allows any HTMLElement type, if want HTMLDivElement just change it
      type: (process.server ? Object : HTMLElement) as PropType<HTMLElement>,
      // let's make it explicit that it does not exist from the begining
      default: undefined,
    },
  },
  setup(props) {
    // Because it can be undefined, let's use `toRef` instead of `toRefs`
    const element = toRef(props, 'element')

    // Optional Effect example
    watchPostEffect((onInvalidate) => {
      // This never happens, on post effect all refs are resolved
      if (!element.value) return

      // Your event listener
      const onScroll = (e: Event) => console.log(e)

      // Add event listener
      element.value.addEventListener('scroll', onScroll, { passive: true })

      // Remove event listener
      onInvalidate(() => element.value.removeEventListener('scroll', onScroll))
    })
  },
})
</script>

这对我来说很有用（Typescript）。

anchorElement: {
  type: (null as unknown) as PropType<HTMLElement | null>,
  required: true,
},
