“如何在cmd提示符下修复heroku上的“应用崩溃”

Question

我正试图在heroku上发布我的应用程序。然而，当我执行< code>heroku open命令时，我发现它在日志中给出了一个“应用程序崩溃”的问题

尝试检查日志并重新启动rails服务器。

heroku日志--app obscure-out-78036

预期的功能是在heroku上启动应用程序。

Answer 1

查看有关日志的文档以及如何在Heroku https://devcenter.heroku.com/articles/logging#log-retrieval 使用它们，并再次询问您是否不清楚日志。

此外，谷歌搜索显示了heroku上rails应用程序的一些典型问题，例如heroku code=H10 desc=“app crash”-无法找出它崩溃的原因
