我正在尝试制作我的第一个 Rails 应用程序，但是当我尝试运行 rails server 时，它只会给我一大堆文本。我在 arch linux 上运行它并使用了 AUR 中的 ruby-rails 包。

[drew@rhino sophia]$ rails server
=> Booting Puma
=> Rails 5.2.0 application starting in development
=> Run `rails server -h` for more startup options
Exiting

请参阅 config/application.rb 中的 config.time_zone 部分。
您可以运行 rake -D time 来显示所有可用的时区。
