可能重复：
HTTPS github access
我正在尝试从在Windows 7上运行的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，似乎都会出现某种错误。如何使克隆工作？
