我也在使用带有 cygwin 的 Windows 7。

从二月份开始，我已经在 Haskell 平台上安装了 happstack-hsp。

我刚从四月安装了 Haskell 平台。我尝试通过 cabal 安装 happstack-hsp 包并得到以下错误：

$cabal install happstack-hsp
Resolving dependencies...
Configuring hsp-0.7.1...
Building hsp-0.7.1...
Preprocessing library hsp-0.7.1...
ghc.exe: could not execute: trhsx
cabal.exe: Error: some packages failed to install:
happstack-hsp-7.1.1 depends on hsp-0.7.1 which failed to install.
hsp-0.7.1 failed during the building phase. The exception was:
ExitFailure 1

我试图然后安装 trhsx，并得到了这个错误：

$cabal install trhsx
Resolving dependencies...
Configuring trhsx-0.2.2...
Building trhsx-0.2.2...
Preprocessing library trhsx-0.2.2...

Trhsx.hs:1:1:
    Could not find module `Prelude'
    It is a member of the hidden package `base'.
    Perhaps you need to add `base' to the build-depends in your .cabal file.
    It is a member of the hidden package `haskell2010-1.1.0.1'.
    Perhaps you need to add `haskell2010' to the build-depends in your .cabal file.
    It is a member of the hidden package `haskell98-2.0.0.1'.
    Perhaps you need to add `haskell98' to the build-depends in your .cabal file.
    Use -v to see a list of the files searched for.
cabal.exe: Error: some packages failed to install:
trhsx-0.2.2 failed during the building phase. The exception was:
ExitFailure 1

我也在cmd中试过这个，得到了同样的结果。我使用haskell已经很多年了，它发生了很大的变化，有什么想法吗？

trhsx现在来自hsx包装。错误的原因是cabal$HOME/.cabal/bin默认安装了可执行文件。但是，默认情况下$HOME/.cabal/bin不在您的范围内。$PATH

如果你把它添加到你的$PATH，那么一切都应该没问题。
