haskell - 如何在 Cabal 中解决“但是给定的安装包实例不存在”？

Question

几天前我使用 cabal 2.4.0.x 开始了一个项目；今天早些时候，在我的工作系统上，一切都很顺利。在我的家庭系统上，也安装了 nixpkgs 的 Linux，在配置上与我的工作系统几乎相同（我认为没有明显的差异），事情进展不顺利。

运行时cabal new-build，我得到以下信息：

 - http-client-tls-0.3.5.3 (lib) (requires build)
 - dhall-1.20.1 (lib) (requires build)
 - FarmDataServer-0.1.0.0 (lib) (first run)

我不确定导致错误的原因以及可能的解决方法。

更新见评论，但一种解决方法是删除~/.cabal.
