Question

我第一次在Heroku中托管了我的应用程序。它适用于我的本地主机，但当我在Heroku上托管它时，它会给出应用程序错误：应用程序出错，无法提供您的页面。请稍后重试。如果您是应用程序所有者，请检查日志以获取详细信息。我检查我的日志和日志是：

Answer 1

如上所示，错误为Error R10 (Boot timeout ) -> Web process failed to bind to $PORT within 60 seconds of launch。我可以想到两件可能导致这种情况的事情：

您的创业公司需要很长时间 - 例如，您在启动时呼叫外部Web服务。
或者您没有收听正确的端口，因此您永远不会绑定到正确的端口。

我猜它是第二个？您使用什么PORT编号？你做这样的事吗？ var port = Number(process.env.PORT || 5000);
