Elements in iteration expect to have ‘v-bind:key‘ directives的解决办法

原代码块

<li v-for="item in list" class="row">
	<router-link :to="about/"+item.id">{{item.text}}</router-link>
<li>

报错：

Avoid using non-primitive value as key, use string/number value instead”
Elements in iteration expect to have 'v-bind:key' directives

解决方法：添加v-bind绑定key且不用对象绑定，用数值或者字符串绑定

<li v-for="item in list" v-bind:key="item.id" class="row">
	<router-link :to="about/"+item.id">{{item.text}}</router-link>
<li>
