Ruby on rails 为什么Rails composer只创建一个没有功能的基本应用程序`打开http'；：404未找到（OpenURI:：HTTPError）

我刚刚完成了详细的解释，并在最后尝试使用Rails Composer。我在Cloud 9和Windows 10上创建应用程序时遇到问题，出现了相同的错误。该应用程序只创建一个基本的rails应用程序，而不创建具有所有额外功能的rails composer应用程序

首先，我尝试使用以下命令创建新项目：

rails new rails-devise-roles -m https://raw.github.com/RailsApps/rails-composer/master/composer

并得到以下错误：

C:/RailsInstaller/Ruby2.2.0/lib/ruby/2.2.0/open-uri.rb:358:in `open_http': 404 Not Found (OpenURI::HTTPError)

我试图在该文件中查找第358行，但在目录C:/RailsInstaller/Ruby2.2.0/lib/ruby/2.2.0中，似乎没有要检查的“open uri.rb”文件

以下是完整的应用程序创建命令及其结果：
