我一直在尝试设置 Cygwin 以连接到 github，但遇到了一些问题。我使用的是 Windows 8，我知道 Windows 8 上的 Cygwin 的用户组和其他方面存在问题。不过我很确定我已经解决了这个问题。至少，我现在可以正确地更改任何文件的权限。无论如何，这是我从 Cygwin 获得的输出

当我运行这个程序时，有一件有趣的事情：
$ ssh-add -l
Could not open a connection to your authentication agent.
我还要指出的是，我可以在 Powershell 上很好地使用 git。

您的 ssh-agent 可能是从 PowerShell 启动文件启动的。这可能是它在那里工作的原因。
更简单的解决方法是启动另一个代理。您可以使用PuTTY 的盛会。在此处查看如何配置您的 shell 来设置与 Pageant 的连接，以便 ssh-add 和 ssh 可以使用它： http://pascal.nextrem.ch/2011/03/11/using-cygwin-ssh-with-putty-pageant/
