我正在尝试在 Heroku 上部署以下入门套件。但是，当我尝试启动它时，它失败了:(
错误：
错误 R10(启动超时(> Web 进程在启动后 60 秒内无法绑定到$PORT
我没有找到可以配置或设置端口的地方。它在 8080 上启动，但仍然失败。

端口绑定超时存在一些问题。
我已经添加了"preinstall": "npm install -g gulp"和
我的Procfile还显示以下内容：

有人可以帮助我为什么它失败吗？我真的很想在 Heroku 上部署这个项目，非常感谢任何帮助来解决！
项目无法绑定端口。
使用process.env.PORT || 8080而不是仅仅8080解决了我的问题。希罗库喜欢这样！
