无法编译xmonad.hs文件

Question

我在一个基于arch的系统上使用xmonad。但在升级后，我无法通过以下方式编译我的xmonad.hs文件

$ xmonad --recompile

我似乎在xmonad的每个模块上都得到了错误，甚至导入XMonad似乎都不起作用。如果有人以某种方式解决了这个问题，请让我知道。

错误消息：

Answer 1

略有关联，

在全新安装XmonadUbuntu20.10时，当我使用sudo apt install xmonad通过apt安装时，我遇到了这个问题。我想这也安装了xmonad-contrib，它位于这里的libghc-xmonad-contrib-dev，因为当我尝试安装它时，我已经安装了它，看看它是否修复了。最终解决这个问题的是cabal-使用cabal install xmonad安装xmonad和xmonad-contrib，然后使用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

以下是我的命令历史记录，如果它有任何帮助的话：

 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!!!

Answer 2

可能是Arch linux上的XMonad包有一些问题。

作为替代方案，您可以尝试使用pacman -s haskell-cabal和cabal install xmonad。
