今天在安装python模块的时候， 出现一个问题：
[root@localhost certs]# easy_install IPy
Searching for IPy
Reading https://pypi.python.org/simple/IPy/
Download error on https://pypi.python.org/simple/IPy/: [Errno 1] _ssl.c:480: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed -- Some packages may not be found!
Couldn't find index page for 'IPy' (maybe misspelled?)
Scanning index of all packages (this may take a while)
