(Not an Answer）我在Windows 10上遇到了同样的问题。我只是按照页面https://www.haskell.org/ghcup/上的所有默认说明重新安装了GHCup
然后我开始遵循https://www.haskell.org/ghcup/steps/的第一步指令（是的，我也是新来的...）
但是当我到达以下部分时，一切都开始下滑：在ghci中使用外部包
尝试cabal-install命令：cabal repl --build-depends asyn，结果如下：

I:\DevData\Haskell\test-cabal>cabal repl --build-depends async

字符串
在这两种情况下，问题显然都来自hashable-1.4.3.0模块（而不是x86_64 PE+文件）。
