我正在尝试在Heroku上部署以下入门工具包。但是，当我尝试启动它时，它会失败：（
错误：
错误R10（引导超时）-> Web进程在启动后60秒内未能绑定到$ PORT
我在任何地方都找不到配置或设置端口的信息。它在8080上启动，但仍然失败。

let listDirectory = fs.existsSync(options.mainHtml) ? false : true;
options.browserSync.init({

端口绑定与超时有关。
我添加了"preinstall": "npm install -g gulp"和
我的Procfile也显示以下内容：
web：gulp
有人可以帮我为什么会失败吗？我真的很想在Heroku上部署这个项目，非常感谢您解决任何帮助！
项目上没有办法绑定端口。
答案 0 :(得分：0)
使用process.env.PORT || 8080而不是8080解决了我的问题。 Heroku喜欢这种方式！
