遇到问题
最近写vue3+ts和组合式API遇到了上面的问题，代码如下：
<template>
</template>
<script setup lang="ts">
import { useStore } from 'vuex'
import { useRoute } from 'vue-router'
import { onMounted } from 'vue'
const store = useStore()
store.dispatch('initMenus')
const route = useRoute()
onMounted(() =>{
console.log(route.path)
})
</script>
<style lang="scss" scoped>
</style>这个是因为在这个组合式onMounted之前调用了store.dispatch('initMenus') 内部包含async/await
解决方法
If you are using async setup(), make sure to register lifecycle hooks before the first await statement.
只要把代码顺序调整如下，报错即可消失：
<template>
</template>
<script setup lang="ts">
import { useStore } from 'vuex'
import { useRoute } from 'vue-router'
import { onMounted } from 'vue'
const route = useRoute()
onMounted(() =>{
console.log(route.path)
})
const store = useStore()
store.dispatch('initMenus')
</script>
<style lang="scss" scoped>
</style>希望可以帮到你。
