(Emitted value instead of an instance of Error) <swiper-slide v-for="img in images">: component lists rendered with v-for should have explicit keys. See https://vuejs.org/guide/list.html#key for more info.

 @ ./src/views/index/index.vue 9:2-184

 @ ./src/router/routes.js

 @ ./src/router/index.js

 @ ./src/main.js

 @ multi ./build/dev-client ./src/main.js

這個報錯你需要主要看  component lists rendered with v-for should have explicit keys

你去vue的官網看一下v-for    https://cn.vuejs.org/v2/api/#key

需要給:key來解決，避免重複

原代碼：

<swiper :options="swiperOption">
    <swiper-slide v-for="(img, key) in images">
        <a :href="img.linkurl">
            <img class="slide-img" v-lazy="img.picurl" style="height: 100%; width: 100%">
        </a>
    </swiper-slide>
    <div class="swiper-pagination" slot="pagination"></div>
</swiper>      

<swiper :options="swiperOption">
    <swiper-slide v-for="(img, key) in images" :key="key">
        <a :href="img.linkurl">
            <img class="slide-img" v-lazy="img.picurl" style="height: 100%; width: 100%">
        </a>
    </swiper-slide>
    <div class="swiper-pagination" slot="pagination"></div>
</swiper>
