在ubuntu 12.04上安装reactive banana-wx

Question

我刚刚完成了Ubuntu 12.04的全新安装，从apt-get下载了haskell-platform，当我尝试安装reactive banana-wx时，我得到了：

cabal install reactive-banana-wx
Resolving dependencies...

Use --force-reinstalls if you want to install anyway.

当我强制重新安装时，我得到：

关于如何解决这个问题，我有什么想法吗?或者我必须等待依赖项更新或haskell-platform的新版本？如果可能的话，我想让一切都接近Ubuntu上的标准安装。

谢谢!

第一:永远不要强制重新安装array或containers。这很可能会导致已安装的软件包大量损坏。

问题(至少有一个)是reactive-banana-wx-0.5.0.0特别依赖于wxcore-0.12.1.7，而wxcore-0.12.1.7又指定了一个依赖array < 0.4。上传到hackage的允许array-0.4.*的wxcore版本是0.13.2.1和0.90。然而，两者都无法在hackage上使用ghc-7.4构建。

通过下载一些包并编辑它们的.cabal文件来放松依赖，可能可以使用ghc-7.4构建reactive-banana-wx，但我不能猜测编辑reactive-banana-wx .cabal文件以允许更新的wx包或由reactive-banana-wx指定的wx包的.cabal文件允许更晚的数组、容器和类似文件。

我建议通知reactive-banana的作者/维护者，让他解决这个问题。

或者，如果您真的热衷于使用reactive banana-wx，可以将您的Haskell实现降级到使用ghc-7.2或7.0。
