Question

我一直试图弄清楚当我部署到heroku时出现的错误 - 我收到错误：

If you are the application owner check the logs for more information.

关于heroku。

当我查看日志时，这是我的输出：

所以状态在最后两行中从500变为404，但网站在本地呈现完美，但我可以在heroku上看到500，然后是'/'上的404

可能是什么问题？

谢谢！

Heroku日志只是说你的应用在＆＃39; /＆＃39;上产生500错误根路由，公共目录中没有favicon .ico（404，找不到文件）。

也许您必须首先将Rails 4设置为STDOUT（因此Heroku可以打印它们） https://devcenter.heroku.com/articles/rails4#logging-and-assets

Heroku记录了我的错误是什么？
