Module Warning (from ./node_modules/vue-loader/lib/loaders/templateLoader.js):
(Emitted value instead of an instance of Error) : component lists rendered with v-for should have explicit keys. See https://v2.vuejs.org/v2/guide/list.html#key for more info. 报错解决

<el-radio-button v-for="item in policyFigureTabs" :key="item.key" :label="item.key">{{item.value}}</el-radio-button>

给循环赋key值:key=“item.key” warn得到解决
