【问题描述】：
在OSX 10.9.2 上全新安装haskell 平台（通过homebrew）(GHC x64 7.6.3) 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 邮件列表中提出的类似问题。 http://www.haskell.org/pipermail/glasgow-haskell-users/2012-February/021780.html
如何安抚ghc-pkg check 并删除这些警告？
CAVEAT：当我说“全新安装”时，我的意思是我已经从头开始安装了 Haskell 平台，并在全局范围内安装了 cabal-1.18.0.3，并将 cabal 的 bin 目录添加到我的路径中。
【问题讨论】：
-
警告抱怨
ghc-mod和hlint。 Haskell 平台中也没有。因此，如果您真的重新安装了 Haskell 平台，您的~/.cabal目录中可能仍然有以前安装的旧包。 -
除了这两个之外还有很多 很多，让我粘贴更新。见上文。
-
我在 Ubuntu (12.04.4 LTS) 上有完全相同的东西，我首先卸载了所有与 Haskell 相关的软件包，然后安装了 haskell-platform 软件包 (2012.1.0.0~debian1 ）。我的主目录中没有 .cabal 文件夹。它抱怨 stm-2.4.2、Cabal-1.18.1.3 等等。
