Question

我试图在防火墙后安装cabal但没有成功。似乎cabal不支持http重定向，有没有办法解决它？

cabal update -v3

按照@Sibi建议，我使用cntlm-0.92.3粘贴了类似的体验。这是我的配置config.ini：

Proxy               proxy.swmed.edu:3128
Listen  127.0.0.1:53124

我首先尝试使用：

./cntlm -c config.ini

然后发生同样的错误：

cabal update -v3

注意：此问题与身份验证不同，因为我们的代理服务器不需要进行身份验证。这个问题是关于http重定向问题。

运行以下命令@Sibi建议：

./cntlm -M http://www.google.com -c config.ini -v

输出可以在http://pastebin.com/zAvZBDVu

找到

Answer 1

阅读日志，我们看到代理是通过https而不是http，错误是＆＃34;不支持的方案＆＃34;因为最近版本之前的cabal没有处理https。在最新版本中，Https传输已添加到cabal中，因此现在应该解决该问题。

cabal无法处理重定向
