vue里报这个错误处理

vue里报这个错误

vue.esm.js?efeb:628 [Vue warn]: Missing required prop: "to"

vue.esm.js?efeb:628 [Vue warn]: Error in render: "TypeError: Cannot read property '_normalized' of undefined"

vue.esm.js?efeb:1897 TypeError: Cannot read property '_normalized' of undefined

 

 

 

 处理方法： <router-link  class="button" >立即购买</router-link>  里要加上to的值

 <router-link to="/food"  class="button" >立即购买</router-link>    /*这是正确的写法*/
