我刚刚安装了Ubuntu 12.04，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...

当我强制重新安装时，我得到：

关于我如何能够解决这个问题的想法，还是我必须等待依赖关系更新或者新版本的haskell-platform？如果可能的话，我想保持一切尽可能接近Ubuntu上的标准安装。
谢谢！
答案 0 :(得分：3)
首先：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破损。
（或至少一个）问题是reactive-banana-wx-0.5.0.0特别依赖于wxcore-0.12.1.7，后者又指定了依赖array < 0.4。允许array-0.4。*上传到hackage的wxcore版本分别为0.13.2.1和0.90。然而，两者都无法使用ghc-7.4构建hackage。
通过下载一些软件包并编辑他们的.cabal文件来放松依赖关系，可能可以用ghc-7.4构建reactive-banana-wx，但我无法猜测是否更有希望编辑反应性香蕉 - wx .cabal文件允许以后的wx包或者reactive-banana-wx指定的.cabal包的wx文件允许以后的数组，容器和类似文件。
我建议通知作者/维护者反应性香蕉并让他将其分类。
或者，如果您真的热衷于使用reactive-banana-wx，请将您的Haskell实现降级为使用ghc-7.2或7.0。
