在使用 ghc 7.8、cabal 1.18.1.3 和 cabal-install 1.18 时，我无法编译简单的 hello world 或使用 cabal install 安装包。 0.2。

当从命令提示符执行 cabal install stm(或任何其他包)时，Windows 显示“ghc.exe 已停止工作”窗口，输出为:

我按照以下步骤安装了(？)GHC 7.8 和 cabal-install

• 已下载 GHC 7.8 RC2 ( http://www.haskell.org/ghc/dist/7.8.1-rc2/ghc-7.8.0.20140228-i386-unknown-mingw32.tar.bz2 )
• 将 tar 的内容提取到文件夹 $GHC$
• 将 $GHC$\bin 和 $GHC$\mingw\bing 文件夹添加到 PATH。
• 已下载预构建的 cabal-install ( http://www.haskell.org/cabal/release/cabal-install-1.18.0.2/cabal.exe )
• 将 cabal.exe 复制到 $GHC$\bin，使其位于路径中
• 运行 cabal 更新
• 运行 cabal install stm(或任何其他包)

在做这一切之前，我卸载了我以前的 Haskell 平台，从 %USER%\AppData\Roaming 中删除了文件夹 cabal 和 ghc，从 Program Files 中删除了其他 haskell 内容> 文件夹。

我不确定 GHC 是否需要任何额外的安装步骤

我需要 GHC 7.8，因为我想试用 GHCJS。

附言:

我还在我的环境变量中添加了 LANG=C，这样编译就不会抛出 UTF-8 编码错误。

cabal --version 显示:

cabal-install version 1.18.0.2
using version 1.18.1 of the Cabal library

这似乎没问题，只是 cabal 库显示为 1.18.1 而不是 1.18.1.3，但我不确定这是不是一个错误。

ghc-pkg list 显示:

c:/ghc-7.8.0\lib\package.conf.d:

** 编辑 **:尝试通过进入其文件夹并运行 ghc 手动编译 stm 会生成相同的错误窗口并提供输出:

编辑 2:实际上，我什至不能用 ghc helloworld.hs 编译一个简单的 hello world:

main = putStrLn "你好，世界!"

使用“-v3”编译会得到以下(非信息性)输出:

最佳答案

其实是GHC的一个bug；它已在 GHC 邮件列表中得到确认，并且有两个人可以复制它 ( ghc's bug manager thread )。

关于windows - 无法使用 GHC 7.8rc2 和 Windows 7(或使用 cabal 安装包)编译简单的 hello world，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22291739/
