haskell - cabal 安装问题

Question

我在使用 cabal 安装软件包时遇到一些问题。发出以下命令:

> cabal install ghc-mod stylish-haskell haskell-docs hdevtools

产生这些错误

Building yaml-0.8.8.3...
Preprocessing library yaml-0.8.8.3...
<command line>: cannot satisfy -package-id aeson-0.7.0.6-b19228a032fb34be4eef122

我还尝试通过运行安装 hdevltools 的 Windows 分支

> cabal install

在克隆的 github 存储库上。然而这也会产生错误。

作为最后的努力，我尝试将远程存储库更改为“stackage”，即

remote-repo: stackage: http://www.stackage.org/stackage/44ea140bd97cbb0f6140d331f8f7f8667a637eda

但这也没有帮助。

感谢所有帮助!

看起来这是一个 Windows 特定问题，cabal 无法移动 haskell-src-exts 发行版中的某些必需文件(该问题也出现在其他软件包中，例如 pandoc)。这可能与此处报告的问题有关:https://github.com/haskell/cabal/issues/1698

我能够通过执行以下操作来安装 haskell-src-exts 软件包:

> cabal unpack haskell-src-exts
> cd haskell-src-exts
> cabal install
