I have tried many methods, but either there is no way to push in, or the display is null and cannot use other APIs

What is expected?

element push in

What is actually happening?

Cannot read properties of undefined (reading 'push')

function1:

import { useRouter } from 'vue-router';
export default {
  setup() {
    // 第一步将useRouter函数执行放在顶部
    const router = useRouter();
    // 第二步在方法里面调用router 
    function toPage(){
      router.push("/about");
    }
    return {
       toPage
    }
  }
}
