当我运行 'npm start' 时出现节点 JS 错误，也许是 KrakenJS？

Question

当我尝试使用 'npm start' 运行我的应用程序时，它会抛出此错误。我已经更新了 Node 和 NPM，但错误仍然引发此错误。我想知道他们是否与 KrakenJS 有问题？

提前致谢

Answer 1

您似乎在尝试运行端口 8000 上的服务器，但某些东西已经在使用它。

Mon, 11 Apr 2016 13:41:08 GMT uncaughtException listen EADDRINUSE :::8000
Error: listen EADDRINUSE :::8000

尝试为您的服务器选择不同的端口或运行进行一些诊断以查看您是否在 8000 上绑定了某些东西。

Answer 2

看起来有些东西已经在侦听端口 8000。尝试运行:

lsof -i:8000

看看它是否列出了进程。您也可以查看 http://localhost:8000

Answer 3

EADDRINUSE 错误告诉您使用的端口已被另一个程序使用，您的应用程序无法使用。尝试检查该端口上的应用程序或仅更改端口本身。
