vue3使用路由实现页面跳转报错：inject() can only be used inside setup() or functional components.

这样写会报错：

<script setup>
import { useRouter } from 'vue-router'
const buttonGoAbout = () => useRouter().push('/about')
</script>

要把useRouter()这个提出来写用一个变量装起来就好了

<script setup>
import { useRouter } from 'vue-router'
const router = useRouter()
const buttonGoAbout = () => router.push('/about')
</script>
