如何在Windows上安装Cabal的“readline”

Question

我想在Windows上使用Cabal安装'readline'。运行命令时，表示找不到readline。 Cabal是最新的。

命令

cabal install readline

输出

cabal: Error: some packages failed to install:

ExitFailure 1

这可能是什么原因？

如果您正在使用包含pacman的msys发行版（windows haskell平台安装程序附带的发行版应该是这样的发行版），那么您可以使用pacman来安装readline库，并且这个应该让你链接它。

另请注意，ghc附带haskeline库，这是一个纯粹的haskell替代readline，更便于携带。
