haskell - 无法编译 xmonad.hs 文件

Question

我在基于 arch 的系统之上使用 xmonad。但是升级后我无法通过编译我的 xmonad.hs 文件
$ xmonad --recompile
我似乎在 xmonad 的每个模块上都出错，甚至 import XMonad 似乎也不起作用。
如果有人以某种方式解决了这个问题，请告诉我。

错误信息:

略有相关，
在全新安装的 中UBUNTU 20.10 当我通过 apt 安装 xmonad 时遇到了这个问题 sudo apt install xmonad .我想这也安装了xmonad-contrib，它位于这里 libghc-xmonad-contrib-dev ，因为当我尝试安装它以查看它是否修复时，我已经有了它。最后修复它的是 cabal-installing xmonad 和 xmonad-contrib 与 cabal install xmonad然后 cabal install --lib xmonad-contrib ，同时在 ~/.xmonad/build 中创建一个构建命令.~/.xmonad/build的内容:

ghc -package xmonad -package xmonad-contrib --make xmonad.hs -i -ilib -main-is main -fforce-recomp -o xmonad

如果有帮助，这是我的命令历史记录:

 1912  ghc-pkg list # to check the output, just as in the question
 1913  cabal install xmonad
 1914  xmonad --recompile
 1915  cabal install xmonad-contrib
 1916  cabal install --lib xmonad-contrib # the previous line gave a warning, so I issued a corrected command.
 1917  xmonad --recompile
 1918  ghc -package xmonad ~/.xmonad/monad.hs
 1919  ghc -package xmonad ~/.xmonad/xmonad.hs # the previous line had a typo, so I had to issue the command again.
 1920  xmonad --recompile
 1921  nano .xmonad/build # when I tried the previous command, it said something about creating the following file, so I created it.
 1922  xmonad --recompile
 1923  chmod u+x .xmonad/build # when I tried the previous command, it complained about the file not being executable and recommended those permissions.
 1924  xmonad --recompile # worked!!!
