vue绝对路径引入背景图 backgroun-image引入问题

::v-deep{
  .el-slider__button-wrapper{
    background: no-repeat 100% 100%;
    background-position: 50%;
    background-size:45px;
    top: -36px;
    background-image:url('~@/assets/ship.png');
    .el-slider__button{
      display: none !important;
    }
  }
}

@前面要加上~
