vue实战项目music-app报错

<template>
  <div class="recommend">
    <div class="recommend-content">
      <div class="recommend-wrapper"></div>
      <div class="recommend-list">
        <h1 class="list-title">哈哈哈哈</h1>
        <ul>

        </ul>

<script>
import {getRecommend} from 'api/recommend.js'
import {ERR_OK} from 'api/config'
export default {
  name: 'singer',
  created () {
    this._getRecommend()
  },
  methods: {
    _getRecommend () {
      getRecommend.then((res) => {
        if (res.code === ERR_OK) {
          console.log(res.data.slider)
        }
      })
    }
  }
}
</script>

按照上方的书写方法，发现报下方的错

解决方法：
将
getRecomend.then((res) => {})改为getRecomend().then((res) => {})
