javascript - vue使用异步组件结合is按需加载组件的问题

<el-tabs v-model="activeName" @tab-click="handleClick" type="border-card">
      <el-tab-pane v-for="item in menu" :label="item.name" :name="item.name" :key="item" :component="item.component"><component :is="item.component"></component></el-tab-pane>
    </el-tabs>

methods: {
    handleClick (tab, event) {
        // 异步加载组件
        let getCompoentIndex = this.menu.findIndex(x => x.name === tab.name)
        let component = this.menu[getCompoentIndex].component
        if (!this.menu[getCompoentIndex].loading) {
          this.menu[getCompoentIndex].loading = true
          Vue.component(component, function (resolve, reject) {
            setTimeout(function () {
              require([`./${component}.vue`], resolve)//比如 abc.vue
            }, 1000)
          })
        }
      }
  }

点击的时候去加载异步组件（可以载入组件），但报下面的错

[Vue warn]: Unknown custom element: <abc> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

尝试为abc组件加上name还是报这样的错，有人知道怎么解决吗？
abc.vue

export default {
    name: 'abc',
}
