我想在Cygwin中的Haskell平臺上安裝一個包。它需要websockets包,最新版本爲0.9.0.1。在Cygwin中安裝Haskell的websockets包時出錯
我的命令看起來像:
cabal install websockets
我在生成過程中收到以下錯誤消息(它下載精):

我有一個默認安裝Cygwin x64和哈斯克爾平臺x64在Windows 7 Pro x64上。有沒有解決這個問題的方法?或者我錯過了一些配置?
我在http://www.haskell.org/pipermail/beginners/2010-June/004357.html,在不使用我的更新版本的陰謀中提到的相同cabal
更新的問題(我不斷收到通知有關更新的版本),但安裝命令口口聲聲說新版本安裝的罰款。我不知道這是否與此有關...
