ruby-on-rails - 无法运行 rails 服务器

Question

我正在尝试制作一个像这样非常简单的 Rails 程序。起初，我通过这个命令在 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，然后我运行这个命令没问题rails db:migrate，但是当我运行时我遇到rails server了这些问题

=> Booting Puma => Rails 6.0.1 application starting in development => Run rails server --help for more startup options *** SIGUSR2 not implemented, signal based restart unavailable! *** SIGUSR1 not implemented, signal based restart unavailable! *** SIGHUP not implemented, signal based logs reopening unavailable!

因为这个问题我很困惑？我是一个新手，正在尝试制作一个简单的程序，所以请帮助我，非常感谢。

根据错误，products_controller在这一行中有一个错字

params.require(:product).permit(:\, :title, ...)

从列表中删除并重:\试。
