Javascript 在 pinia store 中的状态更改后，vue 组件不会更新

我目前正在开发我的第一个vue应用程序，目前正在构建登录逻辑.

import { defineStore } from "pinia";

export const useLoginStatusStore = defineStore('loginStatus', {
    id: 'loginStatus',
    state: () => ({
        isLoggedIn: false
    }),
    actions: {
        logIn() {
            this.isLoggedIn = true
            console.log("Login", this.isLoggedIn)
        },
        logOut() {
            this.isLoggedIn = false
            console.log("Logout", this.isLoggedIn)
        }
    }
})

到目前为止，一切正常，我可以访问组件和路由文件中的状态和操作.

**<roouter.js>**

import { createRouter, createWebHistory } from 'vue-router'
import { createPinia } from 'pinia'
import { createApp, ref } from 'vue'
import { useLoginStatusStore } from '../stores/loginStatus.js'

import App from '../App.vue'
import WelcomeView from '../views/public/WelcomeView.vue'
import SplashView from '../views/public/SplashView.vue'

const pinia = createPinia()
const app = createApp(App)
app.use(pinia)

const loginStatusStore = useLoginStatusStore()
let isLoggedIn = ref(loginStatusStore.isLoggedIn)

console.log("isLoggedIn", loginStatusStore.isLoggedIn)


const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/',
      name: 'splash',
      component: SplashView
    },
    {
      path: '/welcome',
      name: 'welcome',
      component: WelcomeView
    },
    {
      path: '/login',
      name: 'login',
      component: () => import('../views/public/LoginView.vue')
    },
    {
      path: '/signup',
      name: 'signup',
      component: () => import('../views/public/SignUpView.vue')
    },
    {
      path: '/resetpassword',
      name: 'resetpassword',
      component: () => import('../views/public/ForgotPasswordView.vue')
    },
    {
      path: '/home',
      name: 'home',
      component: () => import('../views/protected/HomeView.vue'),
      meta: { requiresAuth: true }
    },
    {
      path: '/sounds',
      name: 'sounds',
      component: () => import('../views/protected/SoundsView.vue'),
      meta: { requiresAuth: true }
    },
    {
      path: '/player',
      name: 'soundPlayer',
      component: () => import('../views/protected/SoundPlayerView.vue'),
      meta: { requiresAuth: true }
    },
    {
      path: '/profile',
      name: 'profile',
      component: () => import('../views/protected/ProfileView.vue'),
      meta: { requiresAuth: true }
    },
    {
      path: '/meditation',
      name: 'meditation',
      component: () => import('../views/protected/MeditationView.vue'),
      meta: { requiresAuth: true }
    },
    {
      path: '/tools',
      name: 'tools',
      component: () => import('../views/protected/ToolsView.vue'),
      meta: { requiresAuth: true }
    }
  ]
})

router.beforeEach((to, from, next) => {
  if (to.meta.requiresAuth) {
    console.log("Router", isLoggedIn.value)
    if (!isLoggedIn.value) {
      next({
        name: 'welcome'
      })
    } else {
      next()
    }
  } else {
    next()
  }
})

export default router

在路由中，它被用于受保护的路由和应用程序中.vue用于条件类呈现.

问题是，当状态更新时，组件中的状态不会更新，组件本身也不会更新.我在piniatry 了$subscribe方法，但没有成功.我知道，我们需要的是能产生react 性的东西.但不知道该怎么做.我非常感谢您在这方面的帮助:)

谢谢你的阅读

**App.vue**

<script setup>
import { RouterView } from 'vue-router';
import DevNavItem from '@/components/header/DevNavItem.vue'
import HeaderItem from '@/components/header/HeaderItem.vue'
import FooterItem from '@/components/footer/FooterItem.vue'
import { useLoginStatusStore } from './stores/loginStatus.js';

const loginStatusStore = useLoginStatusStore()
const isLoggedIn = loginStatusStore.isLoggedIn

console.log("App.vue", loginStatusStore.isLoggedIn)

</script>

<template>
  <DevNavItem />
  <HeaderItem v-if="isLoggedIn" />
  <RouterView :class="isLoggedIn ? 'mainProtected' : 'mainPublic'" />
  <FooterItem v-if="isLoggedIn" />
</template>

<style>
/*FONT-IMPORT*/
@import url("@/assets/font/alegreya_font.scss");

/* GENERAL STYLES */

* {
  padding: 0;
  margin: 0;

.mainProtected {

  height: 83vh;
  overflow: hidden;
}
.mainPublic {

  background-color: #253334;
  background-image: url("./src/img/images/background_partial.png");
  background-repeat: no-repeat;
  background-position: bottom;

}
.logoSmall {
  background: url("./img/icons/main.png") center/contain no-repeat;
  height: 100px;
  width: 100px;
}
.buttonPublic {
  padding: 20px 0;
  text-align: center;
  background-color: #7c9a92;
  color: #fff;
  border-radius: 15px;
  width: 90%;
  text-decoration: none;
  font-size: 24px;
  border: none;
}
</style>

我试着用$subscribe订阅这个州，但没有成功.
