错误编译xmonad.hs

Question

我试图使不同的工作区有不同的布局，我发现了这个模块- https://hackage.haskell.org/package/xmonad-contrib-0.15/docs/XMonad-Layout-PerWorkspace.html。

我在我的XMonad.Layout.PerWorkspace中导入了xmonad.hs并添加了这些行-

onWorkspace ["2"] noBorders monocle $  -- layout l1 will be used on workspace "2".
onWorkspace ["9"] smartBorders Full $  -- layout l2 will be used on workspace "6".

在myLayoutHook中

-- The layout hook
myLayoutHook = avoidStruts $ mouseResize $ windowArrange $ T.toggleLayouts floats $
               mkToggle (NBFULL ?? NOBORDERS ?? EOT) myDefaultLayout

               onWorkspace ["2"] noBorders monocle $  -- layout l1 will be used on workspace "2".
               onWorkspace ["9"] smartBorders Full $  -- layout l2 will be used on workspace "6".

             where
               -- I've commented out the layouts I don't use.
               myDefaultLayout =     tall
                                 ||| noBorders monocle
                                 ||| floats
                                 ||| grid
                                 ||| smartBorders Full

但是我在重新编译xmonad时出错了

> xmonad --recompile                                                                                                                         
XMonad will use ghc to recompile, because "/home/apoorv/.xmonad/build" does not exist.

你错过了一个$..。

一般格式如下：

abc
$ xyz123 
$ xyz456

而你似乎有：

abc
xyz123 $
xyz456 $
