安装管道包后的Haskell

Question

我是 Haskell 的新手，正在为我的班级完成任务。我将它安装在 VSCode 中，下载了它的扩展，一切正常。但是安装 Conduit 库后我收到此错误：

ghc-9.4.7.exe: C:\cabal\store\ghc-9.4.7\hashable-1.4.3.0-1961fe79003fd705645c177b7f4aca0399a4d276\lib\libHShashable-1.4.3.0-1961fe79003fd705645c177b7f4aca0399a4d276.a(#7:LowLevel.o): Not a x86_64 PE+ file.
    ghc-9.4.7.exe: Unknown COFF 4 type in getHeaderInfo.
    panic! (the 'impossible' happened)
      GHC version 9.4.7:

你能帮我吗？提前谢谢您）

Answer 1

（不是答案） 我在 Windows 10 上也遇到同样的问题。 我刚刚按照页面中的所有默认说明重新（第一次）安装了 GHCup https://www.haskell.org/ghcup/

然后我开始遵循 https://www.haskell.org/ghcup/steps/ 的第一步说明 （是的，我也是新人...）

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

我最终得到以下结果：

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

cabal-3.6.2.0.exe: repl failed for test-cabal-0.1.0.0.

I:\DevData\Haskell\test-cabal>cabal --version
cabal-install version 3.6.2.0
compiled using version 3.6.2.0 of the Cabal library

在这两种情况下，问题显然似乎都来自 hashable-1.4.3.0 模块。
