Question

当我尝试使用'npm start'运行我的应用时，它会抛出此错误。我已经更新了Node和NPM，但错误仍然引发了这个错误。我想知道他们是否是KrakenJS的问题？

提前致谢

Answer 1

看起来您尝试在端口8000上运行服务器并且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一些诊断程序，以查看您是否在8000上绑定了某些内容。

Answer 2

看起来有些东西已经在端口8000上侦听了。尝试运行：

lsof -i:8000

并查看它是否列出了该过程。您也可以查看http://localhost:8000

Answer 3

EADDRINUSE错误告诉您已使用的端口已被其他程序使用，并且您的应用程序无法使用该端口。尝试检查该端口上的应用程序或只更改端口本身。

当我运行'npm start'时，节点JS错误，也许是KrakenJS？
