haskell - xmonad 找不到模块 `XMonad' : broken package

Question

嗨，直到几天前，我的 Xmonad 一直运行良好，然后我想我用 Synaptic 安装了一些东西，然后开始提示 Xmonad.Config.Gnome 这是我的 xmonad.hs

import XMonad
import XMonad.Config.Gnome


myManageHook = composeAll [
            (className =? "Pidgin" <&&> title =? "Buddy List") --> doFloat
           , (className =? "Gnome-panel" <&&> title =? "Run Application") --> doFloat
           -- , (className =? "XEyes") --> doShift "7"
           ]


main = xmonad $ gnomeConfig {
         modMask = mod4Mask
       , manageHook = myManageHook <+> manageHook gnomeConfig
       }

当我编译时我得到这个:

ghc --make "xmonad.hs" (nella cartella: /home/giuseppe/.xmonad)
xmonad.hs:2:7:
Could not find module `XMonad.Config.Gnome':
  Use -v to see a list of the files searched for.

Compilazione fallita.

使用 ghc-pkg list 我得到:

The following packages are broken, either because they have a problem

所以看起来有两个包坏了。解决此问题的最佳方法是什么？提前致谢

Answer 1

ghc-pkg 显示的错误表明 unix-2.4.0.0 包在安装 xmonad 后不知何故发生了变化。

只需重新安装 xmonad 和 xmonad-contrib 即可解决此问题。如果您使用 cabal-install 安装它们(即通过运行 cabal install xmonad)，那么只需重新运行该命令即可。如果您使用 Synaptic 或类似工具安装它们，那么我怀疑使用 Synaptic 重新安装会破坏您最近安装的任何破坏 xmonad 的东西。您可能想查看打开的错误以查看这是否是一个已知问题，因为它听起来像是一个损坏的包。如果是这种情况，让某些东西快速运行的最佳选择可能是卸载 xmonad 和 xmonad-contrib，然后使用 cabal-install 重新安装它们。
