【问题描述】：

我刚刚在 Windows 7 上安装了 Python，如上所述 http://docs.pylonsproject.org/projects/pyramid/en/1.4-branch/narr/install.html。我在第 3 步运行 python ez_setup.py 命令时收到以下错误。我从这个 URL http://peak.telecommunity.com/dist/ez_setup.py 去 ez_setup.py

c:\Python27>python ez_setup.py

【问题讨论】：

我发现问题的问题。这是由于可以使用以下命令修复的网络代理。 set http_proxy=user:password@proxyaddress:port。我希望这对某人有帮助

标签： python windows installation setuptools

【解决方案1】：

答案在上面的评论中。

当您使用代理时，有一个 Windows 环境变量用于存储代理设置。

该变量是http_proxy 和安全的https_proxy。

设置该变量的格式如下

set http_proxy=user:password@proxyaddress:port
set https_proxy=user:password@proxyaddress:port

如果没有密码，则执行以下操作

set http_proxy=user@proxyaddress:port

举个例子

set http_proxy=jbrown:jbpass@192.168.0.252:8080
