ColumnList.vue中

<template>
  <div class="row">
    <div v-for="column in list" :key="column._id" class="col-4 mb-4">
      <div class="card h-100 shadow-sm">
        <div class="card-body text-center">
          <img  :src="column.avatar && column.avatar.url" :alt="column.title" class="rounded-circle border border-light w-25 my-3" >
          <h5 class="card-title">{{column.title}}</h5>
          <p class="card-text text-left">{{column.description}}</p>
          <router-link :to="`/column/${column._id}`" class="btn btn-outline-primary">进入专栏</router-link>
        </div>
      </div>
    </div>
  </div>
</template>

export default defineComponent({
  name: 'ColumnList',
  props: {
    list: {
      type: Array as PropType<ColumnProps[]>,
      required: true
    }
  },
  setup (props) {
    console.log(props.list)
    const columnList = computed(() => {
      return props.list.map(column => {
        if (!column.avatar) {
          column.avatar = {
            url: require('@/assets/column.jpg')
          }
        } else {
          column.avatar.url = column.avatar.url + '?x-oss-process=image/resize,m_pad,h_50,w_50'
        }
        return column
      })
    })
    
    return {
      columnList
    }
  }

})

template哪里直接写list就是对的，但是如果用columnList就不对
Invalid prop: type check failed for prop “list”. Expected Array, got Object
但是Home传过来的类型就是数组

    </section>
    <h4 class="font-weight-bold text-center">发现精彩</h4>
    <column-list :list="list"></column-list>
  </div>
</template>

<script lang="ts">
import { defineComponent, computed, onMounted } from 'vue'
import { useStore } from 'vuex'
import { GlobalDataProps } from '@/store'
import ColumnList from '../components/ColumnList.vue'

export default defineComponent({
  name: 'Home',
  components: {
    ColumnList
  },
  setup () {
    const store = useStore<GlobalDataProps>()
    onMounted(() => {
      store.dispatch('fetchColumns')
    })
    const list = computed(() => store.state.columns)
    const biggerColumnLen = computed(() => store.getters.biggerColumnsLen)
    return {
      list: list
    }
  }
})
</script>
