因为标签绑定绑定一个函数的参数中传入一个函数时，不能直接加入括号传承，不支持方法中套方法的操作，

错误：

<u-icon
  name="thumb-up-fill"
  @click.native.stop="
	  $_debounce(addThumbsUp(item.id))
  "
></u-icon>

正确

<u-icon
  name="thumb-up-fill"
  @click.native.stop="
	  $_debounce(addThumbsUp，item.id)
  "
></u-icon>

应该把参数传入函数中以回调的形式去调用，不能直接在标签上嵌套

2. Errors compiling template:目前仅支持解构插槽 l_item,如 v-slot=“{ user }”
   在使用作用域插槽时候这样使用的

<template slot-scope="l_item"></template>

需要在参数两边加大括号文章来源地址https://www.toymoban.com/news/detail-577769.html

<template slot-scope="{ l_item} "></template>
