我正在尝试在RHEL5上安装一个python包（旧的我知道）。
[root@myhost~]# pysetup install shyaml

这没关系，因为这台主机无法访问互联网，但可以通过http代理访问。但我找不到任何如何为http代理配置pysetup。
我已经尝试导出代理变量wget / curl style：
http_proxy=http://proxyhost:3128
HTTP_PROXY=http://proxyhost:3128
https_proxy=http://proxyhost:3128
HTTPS_PROXY=http://proxyhost:3128
有什么想法吗？
