这是一个非常简单的节点应用程序，我无法部署。当我收到链接时，显示：heroku welcome to you new app. Refer to documentation if you need help deploying。日志不显示任何错误（所有日志显示为蓝色）。我该如何解决这个问题？

克隆回购然后做了 git init，git add，git commit

heroku create
heroku git:remote -a safe-forest-59278
heroku apps:create myappName
git push heroku master

Answer 1

根据日志声明

Error R10 (Boot timeout) -> Web process failed to bind to $PORT
within 60 seconds of launch

这只是意味着您尝试连接的端口由于某种原因不可用。

而且很可能你正在指定像

这样的端口

port = 3000

您应该将此行更改为

port = process.env.PORT || 3000

这将允许heroku服务器为您的服务器分配一个可用端口来监听。

为什么会发生这种情况，主要是因为您在开发应用程序时指定的端口，这些端口很可能在生产中可用并打开。

无法在heroku上部署节点应用程序。仅显示欢迎消息
