>此外，我试图查看安装后我的 stack 正在使用的 ghc 版本，这导致缺少相同的属性'ghc822'错误. $ stack ghc---version错误:缺少属性"ghc822"，位于(string):1:54(使用"--show-trace"显示详细的位置信息) 解决方案正如palik所言，更改了解析器版本-在我的情况下是更改 解析器:lts-11.3 到 解析器:lts-9.1 stack.yaml 中的是一种解决方法.我不知道更深层的问题是什么，但是有兴趣知道.I am attempting to build my haskell project on NixOS.Running $ stack build gives the following error.$ stack builderror: attribute ‘ghc822’ missing, at (string):1:53(use ‘--show-trace’ to show detailed location information)What does this error mean and how could I proceed?
