为什么 Rails composer 只创建一个没有功能的基本应用程序？ `open_http': 404 未找到 (OpenURI::HTTPError)
Why is Rails composer only creating a basic app without features? `open_http': 404 Not Found (OpenURI::HTTPError)
我刚刚完成了详尽且解释清楚的 Rails tutorial by Daniel Kehoe，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，出现相同的错误。该应用程序创建但只是一个基本的 rails 应用程序，而不是具有所有额外功能的 Rails 作曲家应用程序。
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
并出现以下错误：
C:/RailsInstaller/Ruby2.2.0/lib/ruby/2.2.0/open-uri.rb:358:in `open_http': 404 Not Found (OpenURI::HTTPError)
我试图在此文件中找到第 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。
下面是完整的应用程序创建命令及其结果：

无法访问您的端点，请尝试：
rails new rails-devise-roles -m https://raw.githubusercontent.com/RailsApps/rails-composer/master/composer.rb
但如果这不起作用，只需从原始文件本地下载 ruby 代码，然后指向本地 rb 文件即可。
在您的终端中：
