我是新来的Haskell时遇到运行下面的代码的问题：运行并编译'Hello，World！'在Haskell
module Main (
main
) where
main = putStrLn "Hello, world!"
SublimeHaskell尝试编译并运行上述使用
runhaskell hello.hs
返回错误
hello.o: getModificationTime: invalid argument (The system cannot find the file specified.)
我也试着用它运行它
ghc --make hello.hs
与相同的错误。当我尝试手工编译的代码中使用命令行
ghc -c hello.hs
运行前，我收到了不同的错误：
CreateDirectory ".": invalid argument (Cannot create a file when that file already exists.)
在另一方面，我可以通过没有问题的REPL运行程序：
ghci
GHCi, version 8.0.1: http://www.haskel.org/ghc/ :? for help
Prelude> putStrLn "Hello, world!"
Hello, world!
如果是相关的，我使用的是Windows 7，我用哈斯克尔平台安装程序安装GHC。
***编辑与-v标志运行上述命令的结果如下：
ghc -v hello.hs

环顾四周后，似乎被列为两个包未找到（dph-seq和dph-par）有已被弃用。
嗯，是的，它肯定是有关您正在使用Windows 7，所以是Haskell的生态系统 - 你怎么安装GHC？随着堆栈，或其他方式？ ......我知道我不应该这样做，但我不禁建议只是改用一些Linux发行版来摆脱这种麻烦。 （但是我听说即使在Windows上，堆栈GHC也应该很容易，所以...） – leftaroundabout
您的驱动器已满吗？ –
不幸的是，我一直在使用Haskell平台安装程序安装GHC，但我一直坚持使用Windows。驱动器没有满 - 剩余8GB的空间。 – Fortunato
