Error in mounted hook: "TypeError: Cannot set property 'container' of undefined"

[d1y]

是我姿势不对吗

<template>
  <div id="app" v-click>
    <div>
      <d-player ref="player" @play="play"></d-player>
    </div>
  </div>
</template>

<script>
import VueDPlayer from 'vue-dplayer'
import 'vue-dplayer/dist/vue-dplayer.css'
export default {
  name: 'App',
  components: {
    'd-player': VueDPlayer
  },
  methods: {
    play() {
      console.log('play callback')
    }
  },
   mounted() {
    // this.player = this.$refs.player.dp
  },
}
</script>
</style>
