我正在尝试制作一个像这样的非常简单的Rails程序。首先，我通过以下命令在Rails中做了一些事情：
rails generate scaffold Product \ title:string desciption:text image_url:string price:decimal
似乎一切运行正常，然后我运行了该命令rails db:migrate没问题，但是当我运行rails server时遇到了这些问题
=> Booting Puma
=> Rails 6.0.1 application starting in development
=> Run rails server --help for more startup options

*** SIGUSR1 not implemented, signal based restart unavailable!
*** SIGHUP not implemented, signal based logs reopening unavailable!

因为这个问题，我感到非常困惑吗？我是新手，正在尝试制作一个简单的程序，所以请帮助我，非常感谢。

的这一行有错字
products_controller从列表中删除params.require(:product).permit(:\, :title, ...)
