vue項目遇到的問題
(Emitted value instead of an instance of Error) <el-breadcrumb-item v-for="item in routepath">: component lists rendered with v-for should have explicit keys. See https://vuejs.org/guide/list.html#key for more info.
原因： 使用v-for時沒有設置key
<el-breadcrumb-item v-for='(item,i) in routepath' :to="{ path: item }">{{ paths[item] }}</el-breadcrumb-item>
修改：
<el-breadcrumb-item v-for='(item,i) in routepath' v-bind:key='i' :to="{ path: item }">{{ paths[item] }}</el-breadcrumb-item>
報錯消失
