近期使用vue3+ts+vite项目打包的时候，遇到一个问题，截图如下：

错误翻译

 Cannot find module '@/store/index' or its corresponding type declarations.

找不到xxx模块或者声明文件

 An import declaration can only be used at the top level of a namespace or module. 

导入声明的文件只能在顶部使用

解决办法：

把import xxx from 'xxx'全部放在顶部（script后）

报错前：

<script setup lang="ts">
import { ref, reactive, onMounted, nextTick } from 'vue'
import { useRouter, useRoute } from 'vue-router'
import type { FormInstance, FormRules } from 'element-plus'
const router = useRouter()
import useStore from '@/store/index'
const storeUser = useStore()
</script>

处理后： 

<script setup lang="ts">
import { ref, reactive, onMounted, nextTick } from 'vue'
import { useRouter, useRoute } from 'vue-router'
import useStore from '@/store/index'
import type { FormInstance, FormRules } from 'element-plus'
const router = useRouter()
const storeUser = useStore()
</script>

再次运行yarn build，成功打包！！！！
