坑1：导入SFC组件的时候，直接波浪线提示错误，导入has no default export，但是编译没问题。

Module '"/Users/xinxiang/ProjectSpace/Practice/Vue/vue3-typescript4.8-issue-6305/src/components/HelloWorld.vue"' has no default export.Vetur(1192)

 解决方案1：Vue3项目，直接将当前工作项目的Vetur禁用就好。

坑2：在Vue3的SFC组件中导入ts内容的时候，from后面，导入的文件地址部分红色波浪线提示：has not been built from source file，但是编译没问题，能通过。

import { useXXStore } from './stores/xxStore'

Output file "Xxxxx.d.ts" has not been built from source file "Xxxxx.ts"

折腾了好几个小时，查了很多资料，正准备去找大咖请教的时候，发现，禁用Vetur的时候好了。。

注意注意注意：

Vue3不要和Vetur搭配是用，而是是用Volar

然后再尝试各种复现问题，启用Vetur，禁用Vue Language Features (Volar)、TypeScript Vue Plugin (Volar)，问题没有复现。问题不再出现了。。。

因此推测，还是跟当时使用的vs code 插件Vetur有关，暂时不再深究。

备注：

我就是用官方的初始 npm init vue@latest 化创建的项目：
