haskell - ghc-pkg 检查黑线鳕警告

Question

在 homebrew 上全新安装 haskell 平台(通过 GHC x64 7.6.3 )(OSX 10.9.2 )我在运行 ghc-pkg check 时收到以下警告(见下文)

Warning: haddock-interfaces: /Users/user/.cabal/share/doc/x86_64-osx-ghc-7.6.3/ghc-mod-3.1.7/html/ghc-mod.haddock doesn't exist or isn't a file

根据文档:

ghc-pkg check
    Check the consistency of package depenencies and list broken packages.
    Accepts the --simple-output flag.

我尝试运行以下命令来生成黑线鳕文档无济于事:

sudo cabal install --reinstall --force-reinstalls --enable-documentation

该命令来自用户在 haskell 邮件列表中的一个类似问题。
http://www.haskell.org/pipermail/glasgow-haskell-users/2012-February/021780.html

我该如何安抚 ghc-pkg check并删除这些警告？

警告 : 当我说“全新安装”时，我的意思是我已经从头安装了 Haskell 平台，并在全局安装了 cabal-1.18.0.3并将 cabal 的 bin 目录添加到我的路径中。

那些黑线鳕警告很烦人，但它们不会引起任何问题，AFAIK。我认为这些警告在 Cabal 1.18 中已修复。我再也见不到他们了。

编辑:好的，所以我们需要遵循 kosmikus 的建议......

mv ~/.cabal ~/.cabal.SAVE
cabal update

这将创建文件 ~/.cabal/config。如果您愿意，可以编辑此文件。

现在尝试构建一些东西，看看问题是否消失了。
