很多破碎的haskell软件包

问题描述

（Arch linux）最近，haskell软件包遇到很多问题。通常，我可以通过更新某些软件包来轻松修复它们，但是可能是导致所有我无法弄清的根本原因。我目前认为，最可能的解释是我在haskell安装过程中的某个地方出错了，因为我没有使用“ haskell平台”，而是在需要它们时从各处随意安装了软件包。我刚刚进行了系统升级，现在运行startx时，结果为this。实际上，它所引用的共享对象文件libHSxmonad-contrib-0.16-AAxGT3H9yrS67i4YFgpjoh-ghc8.10.1.so并不存在，但是有两个以libHSxmonad-contrib结尾的ghc8.0.2共享对象文件（这是我的ghc —-version）确实存在。另外，我记得大多数时候说的大多数软件包都不见了（有些是通过cabal，有些是pacman）。如果有帮助，请查看我的cabal list —-installed，ghc-pkg check和pacman -Q|grep haskell。

解决方法

[Arch Linux] 我不确定这是否相关，但最近我对无休止的 Haskell 包更新的反复频率越来越恼火——在我的情况下，几乎完全由我的 pandoc 安装触发。

分辨率

yay -Syu                        ## system update; alt: sudo -Syu
sudo pacman -R pandoc           ## uninstall pandoc

## ----------------------------------------
## Repeated cycles (~5-6) of the following,until nothing shown:

sudo pacman -Qdt                ## list all packages no longer required
                                ## as dependencies (orphans) ...

sudo pacman -R $(pacman -Qdtq)  ## ... and delete them
## ----------------------------------------

yay -Syu                        ## system update; alt: sudo -Syu

示例输出
