1，require模块时不提示require方法：
解决：
File > Settings > Languages & Frameworks > Node.js and NPM 中，勾选Coding assistance for Node.js
2，报错：app.use() requires a middleware function.
解决：
路由处理时未导出 > module.exports = router;
3，报错：No default engine was specified and no extension was provided.
解决：
路口文件设置模板引擎有误 > app.set('view engine','art');
