使用ghc 7.8 ， cabal 1.18.1.3和cabal-install 1.18.0.2时，我无法编译一个简单的hello world或安装cabal-install 1.18.0.2 。
从命令提示符执行cabal install stm （或任何其他程序包）时，Windows将显示“ghc.exe has stopped working”窗口，输出为：

我按照以下步骤安装（？） GHC 7.8和cabal-install
cabal update 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删除文件夹cabal和ghc，以及Program Files夹中的其他haskell内容。
我不确定GHC是否需要额外的安装步骤
我需要GHC 7.8，因为我想试用GHCJS。
PS ：
我还将LANG=C添加到我的envvariables中，以便编译时不会引发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
这似乎是好的除了cabal库显示为1.18.1而不是1.18.1.3，但我不知道这是一个错误。
ghc-pkg list显示：

**编辑**：试图通过进入其文件夹手动编译stm并运行ghc生成相同的错误窗口，并给出输出：
编辑2 ：其实，我甚至不能用ghc helloworld.hs编译一个简单的hello world：
main = putStrLn“Hello，World！”
用“-v3”编译给出以下（非信息）输出：

这实际上是GHC中的一个bug。 它已经在GHC邮件列表中得到确认，两个人可以重现（ ghc的bug管理器线程 ）。
你的ghc.exe路径和cabal.exe路径应该在你的路径变量中
它为我工作。
