1.配置vite.config.ts

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import path from "path";
export default defineConfig({plugins: [react()],resolve: {alias: {"@": path.resolve(__dirname, "./src"),},},
});

2.配置tsconfig.app.json tsconfig.json tsconfig.node.json
其中："type": ["node"], 只需在tsconfig.json中配置

"compilerOptions": {"type": ["node"],"baseUrl": ".","paths": {"@/*": ["src/*"]},}

3.安装 @types/node 解决类型问题错误 

4.重启vscode使用@
