Git Can'；t通过Capistrano部署Rails应用程序

我尝试在vds上运行我的第一个Rails 3应用程序。所以，我决定用capistrano来做这个。还有Phusion passenger、Nginx、RVM和ruby 1.9.3

我将此链接用作教程-

所以，当我打印

cap deploy:check

然后一切正常：

You appear to have all necessary dependencies installed

我收到一个奇怪的错误：

您需要使用公共存储库地址（除非您想将服务器的ssh密钥提供给GitHub，而您不应该这样做）：

当我的私钥不在进行克隆的机器上时，我遇到了这个问题。
