$ foreman start
创建与我的工作应用的链接 我有一个名为Procfile的文件,其中包含:
web: node server.js
这是我的package.json
{
"name": "node-example",
"version": "0.0.1",
"dependencies": {
"express": "3.1.0",
"jade": "*",
"socket.io": "*",
"underscore": "*"
}
}
所以我用
开始“dynos” $ heroku ps:scale web=1
Scaling web dynos... done, now running 1
$ heroku ps
=== web (1X): `node server.js`
web.1: restarting 2013/09/27 22:10:44 (~ 34s ago)
稍后
$ heroku ps
=== web (1X): `node server.js`
web.1: crashed 2013/09/27 22:11:49 (~ 10s ago)
关于我离开这里的任何想法?
编辑:这是一些日志

});
io.on("connection", function(socket){

});
});
http.listen(app.get("port"), app.get("ipaddr"), function() {
console.log("Server up and running. Go to http://" + app.get("ipaddr") + ":" + app.get("port"));
});
现在我得到了类似的错误。

如果没有创建服务器的Node代码,我无法确定,但是从日志中看起来您没有正在侦听正确的端口。
Heroku为您的应用程序分配一个应用程序必须侦听的端口(设置为“PORT”环境变量)。如果你在60秒内没有连接到这个端口,它将会杀死你的应用程序,这似乎正在发生的事情。
更新: 事实上,基于你的web.1日志条目,看起来你正试图在端口8080上侦听。我认为这不太可能是Heroku提供的端口。您可以从process.env.PORT获取Heroku提供的端口,然后听取它。

尝试在仪表板中查看您至少有一个Dynos。我发现我添加了多个应用程序并使用免费跟踪,因此它会继续在应用程序之间移动Dyno。
祝你好运。
