haskell - 尝试编译时找不到模块 `XMonad`

Question

我看到其他几个人也有同样的问题，但是没有一个解决方案对我有用。下面的命令+输出主要是我试过的。我发帖 1) 因为我一直坚持这个问题 2) 我想在另一篇文章中发表评论，但我没有声誉 :(

我已经重新安装了我的操作系统 (arch linux)，只保留了我的主文件，但是我删除了 .stack、.ghc 和 .cabal 文件夹。

yay -S xmonad xmonad-contrib
堆栈安装 xmonad xmonad-contribsudo ghc-pkg recache

xmonad --recompile:

XMonad will use ghc to recompile, because "/home/trey/.xmonad/build" does not exist.
Error detected while loading xmonad configuration file: /home/trey/.xmonad/xmonad.hs

xmonad.hs:7:1: error:
    Could not find module `XMonad'
    There are files missing in the `xmonad-0.15' package,
    try running 'ghc-pkg check'.
    Use -v to see a list of the files searched for.

... 适用于所有 xmonad 相关模块

ghc-pkg 检查:

Warning: haddock-interfaces: /usr/share/doc/xmonad/html/xmonad.haddock doesn't exist or isn't a file

... 返回大约 800 行左右的此类警告，但由于某些原因无法正常复制，因此我无法复制这些警告。如果您确实需要查看整个输出，我会找到解决方案。

Answer 1

听起来像是 cabal 的问题——我认为在 Arch Linux 上打包有一些困难。

作为替代方案，您可以使用特定的 xmonad 配置手动构建 Haskell 项目，一旦您知道此构建正确，您可以创建一个 ~/.xmonad/build shell 文件，并在此处触发对您的 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?
