Question

我正在尝试使用命令＆＃34; npm start＆＃34; 启动React Js服务器，但它在控制台上显示以下错误：

prateek@localhost:~/WebstormProjects/untitled> npm start

> untitled@0.1.0 start /home/prateek/WebstormProjects/untitled
> react-scripts start

Could not find an open port at localhost.localdomain.
Network error message: getaddrinfo ENOTFOUND localhost.localdomain

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! untitled@0.1.0 start: `react-scripts start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the untitled@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output     above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/prateek/.npm/_logs/2017-09-29T05_33_18_507Z-debug.log

我在Linux上使用npm 5.3.0和8.4.0节点。

下面的npm日志文件：

有人可以告诉我，我该如何解决这个错误？

看起来像其他东西正在开发端口上运行react（端口3000）。运行命令sudo lsof -n -i :3000 | grep LISTEN，然后关闭正在使用该端口的程序或使用sudo kill {PID}（将{PID}替换为使用第一个命令找到的PID）。
