我正在尝试将我的 node.js 应用程序部署到 heroku，但是当我尝试使用工头在本地启动它时出现错误：听 EADDRINUSE。我已经运行了一个 netstat 并 grepped 了端口，没有其他任何东西在使用它，并且当直接作为节点 http 服务器运行时，服务器启动没有问题。

我尝试部署的应用程序正在使用 mongo 和 redis 我不确定这些组件是否会影响从 Foreman 开始的服务器。有人对我可以查看潜在错误的区域有任何建议吗？

foreman start

谢谢。

procfile 只有一个条目： web: node web.js

我已将侦听器设置如下：

var port = process.env.PORT || 5000;
app.listen(port, function() {
    console.log("Listening on " + port);
});

我刚刚在 OS X 上遇到了这个问题。看起来工头默认选择端口 5000，这似乎与 Bonjour/mDNS/UPNP 服务冲突。（从我读过的内容来看。我没有花时间来挑选它。）

但是，您可以通过两种方式更改工头使用的端口：在命令行上指定端口或创建一个 .foreman 文件，其中指定的端口号。

祝你好运，编码愉快！

I had the same issue, Error: listen EADDRINUSE means that a Node server is already running.

Check that you are not running a Node server for the same project locally. If you are working on a GitHub synced project locally (on port 5000 for instance) which is tied to Heroku you cannot run a local Node server for that project as the port will be in use twice.

I was actually running a Node server on a project in a different Terminal window and didn't notice immediately.
