尝试在Cygwin中克隆Git存储库时出现SSL证书问题

Question

可能重复:
HTTPS github访问

我正在尝试从运行在Windows 7上的Cygwin克隆一个Git存储库.我正在输入命令git clone http://github.com/scottgonzalez/node-chat并获得此结果:

Cloning into node-chat...
error: SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify
    failed while accessing https://github.com/scottgonzalez/node-chat/info/refs

fatal: HTTP request failed

每当我尝试在Cygwin中执行涉及https URL的任何操作时,我似乎都会遇到某种错误.如何使克隆工作？
