报错如下

found in

---> <VueMarquee>
       <Index> at src/pages/Index.vue
         <App> at src/App.v

我的代码

			<vue-marquee style="height:28px" :showProgress="false" direction="top">
				<vue-marquee-slide v-for="item,i in ads" :key="i">
					<PhoneMoney :phone="item.phone" :money="item.money" />
				</vue-marquee-slide>
			</vue-marquee>

我这边运行时正常的

为什么你的 v-for 写起来怪怪的 v-for="item,i in ads", 不应该使用括号括起来吗? v-for 官方文档

<vue-marquee style="height:28px" :showProgress="false" direction="top">
-  <vue-marquee-slide v-for="item,i in ads" :key="i">
+  <vue-marquee-slide v-for="(item, i) in ads" :key="i">
    <PhoneMoney :phone="item.phone" :money="item.money" />
  </vue-marquee-slide>
</vue-marquee>

虽然写法不标准，但是我保证能用

I can produce this with very simple demo.

<vue-marquee class="flex space-x-2.5">
    <vue-marquee-slide v-for="pack in packs" :key="pack.id">
        content here
    </vue-marquee-slide>
</vue-marquee>

What I mean is I can reproduce same error : TypeError: Cannot read property '$parent' of null in my local demo, its very basic content. packs is consider as array.

Could you please provide the minimum reproducible code?

Thank you, I don't need it now.

导致这个的原因是没给ads一个初始值，它的值不能是个空数组，也可以用v-if判断显示
