vue keep-alive 缓存 不生效解决方案

参考

<keep-alive>
    <router-view v-if="$route.meta.keepAlive"></router-view>
</keep-alive>
<router-view v-if="!$route.meta.keepAlive"></router-view>

错误写法

<keep-alive v-if="$route.meta.keepAlive">
    <router-view></router-view>
</keep-alive>
<router-view v-else></router-view
