Question

在运行cabal安装grapefruit-ui-gtk时，我在依赖项TypeCompose上生成了构建错误。我运行的确切命令是

cabal install grapefruit-ui-gtk

并获得以下错误输出：

GHC版本：

荣耀的格拉斯哥Haskell编译系统，版本8.4.3

Cabal版本：

使用2.2.0.1版的阴谋图书馆

什么可能导致此问题？我尝试将其安装在带有cabal init的新目录中，但这似乎没有任何效果。

Answer 1

这是known issue，TypeCompose低于8.4，has been fixed但尚未放入Hackage。

您也许可以使用较早版本的GHC（请参阅this question）（例如8.2.2）来配置cabal命令，而不会出现此问题。

或者，使用stack，这将使您可以按项目切换ghc版本，并在LTS resolver上为8.2.2提供TypeCompose。

无法在Windows 10上安装Grapefruit
