我看到其他几个人遇到相同的问题，但是没有一个解决方案对我有用。以下命令和输出主要是我尝试过的。我正在发布1），因为我在此上停留了一段时间，并且2）我想在其他帖子上发表评论，但我没有声誉：（
我重新安装了操作系统（arch linux），仅保留了我的主文件，但是我删除了.stack，.ghc和.cabal文件夹。

听起来像Cabal的问题-我认为Arch Linux上存在一些打包困难。
作为替代，您可以使用特定的xmonad配置手动构建Haskell项目，一旦知道正确构建，就可以创建~/.xmonad/build shell文件，并在此处触发对xmonad配置/应用程序的构建。
所以build的内容可能是：
#!/usr/bin/env bash
set -e
cd ~/MyXmonadProject/
stack build # or cabal build?
