"定义pysetup的代理"

Question

我正在尝试在RHEL5（我知道的旧版本）上安装一个python包。你知道吗

[root@myhost~]# pysetup install shyaml
Checking the installation location...
Getting information about 'shyaml'...
extensions in requires.txt are not supported (used by u'pip' 6.0.6)

Traceback (most recent call last):

这是可以的，因为此主机没有访问internet的权限，但是可以通过http代理进行访问。但是我找不到任何关于如何为http代理配置pysetup的信息。你知道吗

我已经尝试导出代理变量wget/curl样式：

http_proxy=http://proxyhost:3128
HTTP_PROXY=http://proxyhost:3128
https_proxy=http://proxyhost:3128
HTTPS_PROXY=http://proxyhost:3128

你知道吗？你知道吗
