我已经将一个个人项目从Vue 2迁移到Vue 3，但是偶然发现了一个错误，我似乎不知道如何修复-所以我希望这里有人可以帮助我。
我试过用谷歌搜索，从多个网站上阅读了大量的帖子和文档。但没有什么能让我更接近。
我试图重组Vuex商店，因为一个线程建议，但它没有什么区别。我试图改变导入的相对路径，但没有什么区别。我试图删除组件中的存储，以确保组件按预期工作-它确实工作。
所以现在我希望这里有人能帮助我，因为我想我只是问了错误的问题，寻找错误的答案。
所以我们来原谅我可怜的代码，还在学习。

我很抱歉的许多行代码-只是希望有人发现我犯的错误。如果需要其他信息，请告诉我。
先谢谢你了。
编辑：正如Estus Flask提到的：

export default store(function (/* { ssrContext } */) {
  const Store = createStore<StateInterface>({
    modules: {
      alarmStore: alarm, // I updated this
      melodyStore: melody, // And this
    },

    // enable strict mode (adds overhead!)
    // for dev mode and --debug builds only
    strict: !!process.env.DEBUGGING,
  });

  return Store;
});
