由于找不到 staging.log ，我们的 heroku staging 应用程序在启动时崩溃。这似乎很奇怪，因为它应该只是将所有内容输出到 development.log，所以我不确定发生了什么。

任何帮助将不胜感激！谢谢！

这是堆栈跟踪：

您的应用程序应该将其日志输出到 STDOUT，而不是服务器上的文件。有关详细信息，请参阅开发中心上的日志记录文章：https ://devcenter.heroku.com/articles/logging

Heroku 在部署时自动将rails_log_stdout注入到您的应用程序中，这修复了 Rails 默认日志记录，所以我不确定为什么这里没有发生这种情况。当您部署到 Heroku 时，您是否看到以下行输出？

-----> Rails plugin injection
   Injecting rails_log_stdout
   Injecting rails3_serve_static_assets

如果您有 config/environments/staging.rb 文件，请确保您已将 RACK_ENV 和 RAILS_ENV 都设置为“staging”。

heroku config:add RACK_ENV=staging --app myapp-staging
heroku config:add RAILS_ENV=staging --app myapp-staging

您是否有一个Procfile来指定您要运行的环境？我不相信 Heroku 要求这样做，但它允许您指定环境等。
