我擦除并重新安装了Haskell平台（Haskell.org：cabal、stack、ghc），但是现在没有插件包可以正确安装。阴谋集团总是以ExitFailure1结尾。可能是因为无法找到依赖项。但是，在大多数情况下，它是主要软件包，由于某些原因它无法解决。 有这种现象的经验吗？

解决Cabal软件包损坏的问题：在OSX中有一个“ Frameworks”目录。它保留了一个Haskell框架，您需要删除它，否则ghc会在后台保持活动状态，并且用cabal构建软件包会失败。通常，您需要删除（隐藏的）.cabal，.stack和.ghc目录，以及“框架”中的Haskell框架。在〜/ Library和〜/ User / Library中还有两个（！）Haskell目录，最好删除。
在寻找Rails框架时偶然发现了这一点。谢谢大家为可能的解决方案做出贡献！
