Node.js表示NPM启动错误，退出状态8
我刚刚在Amazon EC2上安装了node.js，并且一切正常，然后我停止了服务器，并试图再次启动，现在我得到这个错误：

我所做的只是重命名为server.js server.js，我也改变了package.json，但它的工作后，直到我停止服务器？

问题是端口已被使用，或者您没有权限绑定该端口。
尝试更改HTTP服务器的侦听端口或使用sudo node app.js以root身份运行服务器
如果你遇到和我一样的情况，这里是如何closures快递。
ps aux | grep node Find the process ID (second from the left): kill -9 PRCOCESS_ID
使用Express 4时，启动脚本位于./bin/www
如果你有这个错误（像我一样），只需编辑它并replace
app.set('port', process.env.PORT || 5000);
通过
app.set('port', process.env.PORT || YOUR_PORT_NUMBER);
