Haskell：安装Yesod / Snap时出现问题，我想在Windows 7上通过cabal接收其他任何软件包

Question

我是Haskell的新手，正在尝试在Windows 7上安装Snap（ http://snapframework.com ）。我已经安装了GHCi和cabal。 开始执行与网站文档中所述相同的操作，但我有下一个例外：

Yesod发生了相同的事情，因此似乎是cabal在Windows 7上并不是很好的作品，或者在开始通过cabal安装任何软件包之前需要应用一些魔术配置。

Answer 1

但是即使我这样做

C:\Users\Bogdan>cabal update

有同样的问题

Downloading the latest package list from hackage.haskell.org
Warning: http error: Network.Browser.request: Error raised ErrorParse
"parseResponseHead Response status line parse failure: <html>\r\n"
cabal: Network.Browser.request: Error raised ErrorParse "parseResponseHead
Response status line parse failure: <html>\r\n"

我当然可以上网。 如果是防火墙或代理问题，则仅发生在Haskell。 它使用一些特殊的配置文件吗？

Answer 2

如果您位于代理后面，则可能需要将代理设置添加为HTTP_PROXY和HTTPS_PROXY环境变量，而不仅仅是依赖于适用于Web浏览器的代理自动配置。
