Storing debug log for failure in /root/.pip/pip.log

pi@cohoserver ~ $ sudo git clone https://github.com/ziahamza/webui-aria2.git
Cloning into 'webui-aria2'...
**error: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none while accessing https://github.com/ziahamza/webui-aria2.git/info/refs

Git Clone 也遇到这样的问题。

终于解决掉问题了，原来是树莓派的时间设置问题，现在一切完美了。
所有的SSL问题都搞定。

我这里目前没法访问 https://pypi.python.org/simple 即使翻墙。建议改用 douban(http://pypi.douban.com/simple) 或 v2ex(http://pypi.v2ex.com/simple) 的源。将下面内容加到 ~/.pip/pip.conf 中
