全新安装 haskell 平台后(通过homebrew
) (GHC x64 7.6.3
) on OSX 10.9.2
当我运行时,我收到以下警告ghc-pkg check
(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,但无济于事:
sudo cabal install --reinstall --force-reinstalls --enable-documentation
该命令来自用户在 haskell 邮件列表上提出的类似问题。http://www.haskell.org/pipermail/glasgow-haskell-users/2012-February/021780.html 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?
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,并进行了全局安装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,但据我所知,它们不会造成任何问题。我认为这些警告已在 Cabal 1.18 中修复。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,您可以编辑此文件。
现在尝试构建一些东西,看看问题是否消失。
