Node.js 设置Sequelize

我第一次对编程、熟悉节点和设置数据库很陌生。所以请给我一些关于我做错了什么的建议。我创建了一个默认的express应用程序。然后运行它得到这个错误

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: listen EADDRINUSE
    at errnoException (net.js:904:11)
    at Server._listen2 (net.js:1042:14)
    at listen (net.js:1064:10)
    at Server.listen (net.js:1138:5)
    at Function.module.exports (D:\Developer\DurexData\app.js:69:30)
    at null.<anonymous> (D:\Developer\DurexData\node_modules\sequelize\lib\emitt
ers\custom-event-emitter.js:105:15)
    at emit (events.js:95:17)
    at module.exports.CustomEventEmitter.emit (D:\Developer\DurexData\node_modul
es\sequelize\lib\emitters\custom-event-emitter.js:61:33)
    at module.exports.finish (D:\Developer\DurexData\node_modules\sequelize\lib\
query-chainer.js:142:30)
    at exec [as fct] (D:\Developer\DurexData\node_modules\sequelize\lib\query-ch
ainer.js:96:16)

models/index.js

routes/index.js

routes/user.js

谢谢大家

问题解决了，我从sequelize代码中添加了http创建服务器，并让app.listen-in./bin/www没有注意到这就是导致此错误的原因。

EADDRINUSE表示您尝试将express服务器绑定到的端口上已有其他内容正在侦听。这与sequelize无关
