Question

npm i pinia -D

修改渲染进程入口文件，加载 Pinia 插件：

src/renderer/main.ts

import {createApp} from 'vue';
import {router} from './router';
import { createPinia } from "pinia";
import App from './App.vue';
import './style.css';
import "./assets/icon/iconfont.css";

createApp(App).use(createPinia()).use(router).mount('#app');
