vue组件支持预处理语言的关键点：

<style rel="stylesheet/scss" lang="scss">  
  .mint-swipe {  
    height: 300px;  
    .mint-swipe-indicators {  
      width: 98%;  
      text-align: right;  
      left: 0;  
      transform: translateX(-0);  
      .mint-swipe-indicator {  
        opacity: .8;  
        background: #ddd;  
      }  
      .is-active {  
        background: #2745FF;  
      }  
    }  
    img {  
      width: 100%;  
      height: 100%;  
      object-fit: cover;  
    }  
  }  
</style>  

只需要在style加上rel=”stylesheet/scss”就能正确识别scss代码啦，相同less也是一样的
