错误的引入方式：
export default { data () { return{ imgUrl_homePage:‘@/assets/img/homePage_active.png‘ } } }
因为webpack是按字符号打包的，正确的引入方式：
1.import在外部引入
import img_url from ‘@/assets/img/homePage_active.png‘ export default { data () { return{ imgUrl_homePage:img_url } } }
2.require内部引入
export default { data () { return{ imgUrl_homePage:require(‘@/assets/img/homePage_active.png‘） } } }
