Mac上的hoogle 4.2.34安装错误w“无法匹配预期类型'CompilerId'”

Question

警告：此处有新的Haskell用户

我正在尝试在Haskell Platform 2014.2.0.0上为Mac OS X Maverick（64位）安装Hoogle的CLI版本。我已经安装了cabal 1.21.0.0和ghcjs支持以及ghc 7.8.3。

以下是运行$cabal install hoogle

的输出

    Couldn't match expected type ‘CompilerId’
                with actual type ‘Maybe CompilerId -> CompilerId’
Probable cause: ‘comp’ is applied to too few arguments
    In the fourth argument of ‘finalizePackageDescription’, namely
      ‘comp’
    In the expression:
      finalizePackageDescription [] (const True) plat comp [] pkg
cabal: Error: some packages failed to install:
hoogle-4.2.34 failed during the building phase. The exception was:
ExitFailure 1

我已经提出了一个问题：https://github.com/ndmitchell/hoogle/issues/84。我正在尝试整理拉动请求来修复它。

编辑没关系，这不是Hoogle中的错误。你和我都有一个实验性的Cabal安装了一个突破性的变化。目前还没有办法调整Hoogle。如果您要安装，只需使用cabal install hoogle --constraint 'Cabal < 1.21'。
