Vite无法识别src文件夹？SvelteKit+Socket.IO项目启动报错

我有一个使用Socket.IO实现WebSocket通信的SvelteKit项目，需要在vite.config.ts的插件中运行WebSocket服务器初始化函数。vite.config.ts本身无语法错误，但执行npm run dev时，出现无法找到'src'包的模块缺失错误。此前该配置可正常运行，现在问题出现在首次使用import x from "src/..."的导入语句处。我已在svelte.config.js、vite.config.ts和.svelte-kit/tsconfig.json中配置了src别名，但报错依然存在。尝试过重启编辑器、更换导入方式、重启电脑均无效。

相关代码与配置 #

vite.config.ts #

import { defineConfig } from 'vite';
import { sveltekit } from '@sveltejs/kit/vite';
import type http from 'http';
import initSocketIoServer from './src/lib/server/socketIoServer';
export default defineConfig({
    plugins: [
        sveltekit(),
        {
            name: 'vite-plugin-socket-io',
            configureServer(server) {
                initSocketIoServer(server.httpServer as http.Server);
            },
        },
    ],
});
