如何将Macchiato clojurescript应用程序部署到Heroku免费帐户？
我尝试通过以下命令创buildMacchiato（ClojureScript模板）的空白应用程序：
lein new macchiato abc cd abc git init heroku create git add --all git commit -m "Initial" git push heroku master heroku run lein package 但应用程序崩溃。
我应该怎么做免费的Heroku上运行Macchiato / ClojureScript空白应用程序？
来自Heroku的一些日志：

这应该是问题的根源
2017-09-20T14:20:23.735706+00:00 app[web.1]: INFO [abc.core:19] - abc started on 127.0.0.1 : 46297
该应用程序只听取了127.0.0.1，但是，heroku期待您的应用程序在0.0.0.0上侦听。
添加一个环境variablesHOST ，值为0.0.0.0可以解决问题。
