引导程序后的Ruby on Rails在静态页面上安装HTML而不显示

I am creating a website for a friend using ROR like and am formatting using Bootstrap. I creates a couple of static pages, for example a home page. After running bundle install and adding bootstrap css framework,and restarting the server none of the html written on any of the pages is showing up. However, the application.html.erb is rendering just fine, but it's just a simple header.I am creating a website for a friend using ROR
