在homebrew上全新安装haskell-platform（通过GHC x64 7.6.3）（OSX 10.9.2）后，当我运行ghc-pkg check时，我收到以下警告（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haddock文档无效：
sudo cabal install --reinstall --force-reinstalls --enable-documentation
该命令来自用户在haskell邮件列表上的类似问题。 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＆＃34;全新安装＆＃34;我的意思是我已经从头开始安装Haskell平台，并在全球范围内安装cabal-1.18.0.3并将cabal的bin目录添加到我的路径中。
答案 0 :(得分：4)
那些黑线鳕警告令人讨厌，但它们不会引起任何问题，AFAIK。我认为警告已在Cabal 1.18中修复。我再也看不到他们了。
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，看看问题是否已经消失。
