当推送到heroku时，我收到错误：
remote: ! Precompiling assets failed.
remote: !
remote: ! Push rejected, failed to compile Ruby app.
remote:
remote: ! Push failed
我仍然需要在Ruby中添加一些变量，但我认为这应该可行。我对Rails很新，有没有更好的方法来设置html页面？我之前在这个应用程序的Python版本上使用过此代码。

答案 0 :(得分：2)
我要拖出陈词滥调，但我认为这是适用的：
“相关并不意味着因果关系。”
您可能在遇到此异常之前已将资产添加到Rails项目中，但这并不意味着这些资产是异常的原因。 SIGTERM是源自项目外部的UNIX信号，或多或少归结为“请关闭”。通过这样做，您的应用程序可以慷慨地满足此要求。
Heroku dyno manager可能是此信号的来源。如果您正在使用Heroku的免费套餐，由于该级别的dynos必须有睡眠时间，您将不时遇到此问题。
尝试运行：
重新启动工作人员dynoheroku restart worker.1
关于这个问题并非来自dyno经理，请尝试将您的网络服务器更改为生产等级产品。 Heroku特别cautions against using WEBrick，可以用于开发，但对生产来说不太好。虽然您目前可能正处于开发阶段，但您可能希望咬紧牙关并使用与最终将在生产中运行的相同设置。
我不认为WEBrick在这里是个问题，但你现在可能会把你的鸭子连在一起而不是以后。
