[Vue warn]: Invalid prop: type check failed for prop "count". Expected Number with value 0, got Stri

代码

   <Badge :count="count">
                <router-link to="/News">
                  <img class="demo-badge" src="static\pictureV1.0\Tobar\消息 (3).png" />
                </router-link>
              </Badge>

data

 data() {
    return {     
      count: "",      
    };
  },

错误原因

count: “”, 不能为字符串，需要为int 整数
