Question

我在使用基本的nodejs和express程序时遇到了一些麻烦。

问题是当我使用npm start时应该运行node。\ bin \ www我收到这些错误：

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

cdc-api@0.0.0 start C:\Users\{USRNAME}\Desktop\projets\cdc\cdc-api
node .\bin\www

我已经尝试了我在互联网上找到的所有内容（重新安装节点，重新创建package.json，...）我无法让它工作。

仅供参考，我在Windows 8上（如果有任何帮助的话）

提前感谢您的帮助（和女孩;））。

Answer 1

错误＆＃34; EADDRINUSE＆＃34;表示您尝试使用的端口已被您的系统使用。尝试更改应用中使用的端口或关闭使用它的任何程序。

Answer 2

错误表示该端口当前正在使用中。更新代码以使用其他端口。通常，node.js / express示例会在app.js中分配端口。

Answer 3

EADDRINUSE在您的代码使用另一个程序的相同端口时发生。您可以尝试使用另一个端口查看问题是否解决。

无法启动nodejs + express基本程序
