无法启动Node.js + Express基本程序

我在使用基本的nodejs和express程序时遇到了麻烦。

问题是，当我使用npm start哪个应运行节点。\ bin \ www时，出现以下错误：

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

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


events.js:72

这是npm-debug.log中的内容：

我已经尝试了在互联网上找到的所有内容（重新安装节点，重新创建package.json，...），但我无法使其正常工作。

仅供参考，我在Windows 8上（如果有帮助）

预先感谢您对男人（和女孩；）的帮助。
