我试图将引导程序包括到示例web项目第5章Hartl的Rails教程中，出现错误：

链轮：：StaticPageshome中的循环依赖错误

显示/home/ror/rubys/sample_app/app/views/layouts/application.html.erb，其中第5行>出现：

/home/ror/rubys/sample_app/app/assets/stylesheets/application.css已经是必需的

application.html.rb

尝试删除app/assets/stylesheets/application.css

此外，application.html.rb文件中还有一个输入错误。在custom.css中添加@import bootstrap的额外原因？
