Node.js express NPM启动错误，退出状态为8。

javascriptnode.jsamazon-ec2

我刚刚在亚马逊EC2上安装了Node.js，一切正常工作。然后我停止了服务器，尝试重新启动它，但现在出现了以下错误：

我所做的只是将app.js重命名为server.js，我也在package.json中进行了更改，但它仅在停止服务器之前起作用。

问题是该端口已被占用，或者您没有权限绑定该端口。

尝试更改HTTP服务器的监听端口或使用sudo node app.js以root身份运行服务器。

我已经尝试过了，但端口被占用可能是问题所在，感谢提供信息。 - user2559108

你检查过使用该端口的程序了吗？netstat -a - Pedro Nasser
我将应用程序设置为监听端口8080，该端口重定向到端口80，该端口似乎未被使用，我已将输出添加到问题中。 - user2559108

如果您遇到与我相同的情况，以下是如何关闭Express：

ps aux | grep node
Find the process ID (second from the left):
kill -9 PRCOCESS_ID
给出进程ID # lsof -P | grep ':3000' | awk '{print $2}' - Wade Anderson

使用Express 4时，启动脚本位于./bin/www

如果你遇到这个错误（就像我一样），只需编辑并替换它

app.set('port', process.env.PORT || 5000);

由

app.set('port', process.env.PORT || YOUR_PORT_NUMBER);
