我发现 bootstrap-sass 这个 gem 的安装路径和你 web 项目的路径必须在一个硬盘路径里，否则就会报错，有谁能指点一下啊。 ArgumentError in Static_pages#home

Showing E:/sample_app/app/views/layouts/application.html.erb where line #5 raised:

different prefix: "d:/" and "E:/sample_app/app/assets/stylesheets" (in E:/sample_app/app/assets/stylesheets/custom.css.scss)
