编译成字节小程序后有的组件挂载不上

<template>  
    <view class="content">  
        <cc ref="cc"></cc>  
        <aa ref="aa"></aa>  
        <ee ref="ee"></ee>  
        <!-- <dc ref="dc"></dc> -->  
    </view>  
</template>  

<script>  
    import aa from "@/pages/aa/index/index.vue"  
    import cc from "@/pages/cc/index/index.vue"  
    import dc from "@/pages/dd/index/index.vue"  
    import ee from "@/pages/ee/index/index.vue"  

    export default {  
        components: {  
            ee,  
            dc,  
            aa,  
            cc,  
        },  
        data() {  
            return {  
                title: 'Hello'  
            }  
        },  
        onShow() {  
            setTimeout(() => {  
                console.log(this.$refs, 'refs组件22引用实例')  
            }, 2000)  
        },  
        methods: {  

        }  
    }  
</script>

pages.json中你已经把这个两个组件注册成页面了 才导致你出现这个问题的
