無法啓動nodejs + express基本程序

我對基本nodejs和express程序有點麻煩。無法啓動nodejs + express基本程序

問題是，當我使用npm start應該運行節點\ BIN \ WWW我得到這些錯誤：

C:\Users\{USRNAME}\Desktop\projets\cdc\cdc-api>npm start 

[email protected] start C:\Users\{USRNAME}\Desktop\projets\cdc\cdc-api 
node .\bin\www

和這裏是我在NPM-的debug.log：

我已經嘗試了所有我在互聯網上找到的東西（重新安裝節點，重新創建package.json，...）我無法讓它工作。

僅供參考，我在Windows 8（如果它的任何幫助）

預先感謝您的幫助球員（女孩））。

錯誤「EADDRINUSE」表示您嘗試使用的端口已被您的系統使用。嘗試更改應用中使用的端口或關閉正在使用的任何程序。

作爲一個後續，檢出libuv [這裏]的錯誤代碼列表（http://nikhilm.github.io/uvbook/basics.html#error-handling）。這將極大地幫助您調試Node應用程序。 – 2014-10-21 22:04:10

-_-我一定是地球上最倒黴的人，我曾考慮過這個，試圖改變它三次，但沒有改變任何東西。謝謝！！ – Moucheg 2014-10-21 22:13:26

該錯誤表示該端口當前正在使用中。更新代碼以使用不同的端口。通常情況下，node.js/express樣本將分配app.js中的端口。
