问题描述
在新安装的haskell平台上（通过 homebrew ）（ GHC x64 7.6.3 ） OSX 10.9.2 运行 ghc-pkg check 时会收到以下警告（见下文） 警告：haddock-interfaces：/Users/user/.cabal/share/doc/x86_64-osx-ghc-7.6.3/ghc- mod-3.1.7 / html / ghc-mod.haddock不存在或不是文件
警告：haddock-html：/Users/user/.cabal/share/doc/x86_64-osx-ghc -7.6.3 / ghc-mod-3.1.7 / html不存在或不是目录
警告：haddock-interfaces：/Users/user/.cabal/share/doc/x86_64-osx- ghc-7.6.3 / hlint-1.8.59 / html / hlint.haddock不存在或不是文件
警告：haddock-html：/Users/user/.cabal/share/doc/x86_64 -osx-ghc-7.6.3 / hlint-1.8.59 / html不存在或不是目录
警告：haddock-html：/usr/local/Cellar/haskell-platform/2013.2.0.0 /share/doc/mtl-2.1.2/html不存在或不是目录
警告：haddock-interfaces：/ usr / local / Cellar /haskell-platform/2013.2.0.0/share/doc/transformers-0.3.0.0/html/transformers.haddock不存在或不是文件
警告：haddock-html：/ usr / local / Cellar /haskell-platform/2013.2.0.0/share/doc/transformers-0.3.0.0/html不存在或不是目录
警告：haddock-interfaces：/ usr / local / Cellar / haskell-platform /2013.2.0.0/share/doc/case-insensitive-1.0.0.1/html/case-insensitive.haddock不存在或不是文件
警告：haddock-html：/ usr / local / Cellar /haskell-platform/2013.2.0.0/share/doc/case-insensitive-1.0.0.1/html不存在或不是目录
每份文件：
ghc-pkg检查
检查一致性包裹依赖性和列出破碎的包裹。
接受--simple-output标志。
我尝试运行以下命令来生成haddock文档无济于事：
sudo cabal install --reinstall --force-reinstalls --enable-documentation
该命令来自用户在haskell邮件列表中的类似问题。
如何安抚 ghc-pkg check 并删除这些警告？
CAVEAT ：当我说全新安装时，我的意思是我安装了Haskell-从全新的平台开始安装，并全局安装 cabal-1.18.0.3 并将cabal的bin目录添加到我的路径中。 解决方案
这些haddock警告令人讨厌，但它们不会引起任何问题，AFAIK。我认为警告在1.18版中得到了解决。编辑：好的，所以我们需要遵循kosmikus的建议......
/ p>
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。
现在尝试构建一些内容并查看问题是否消失。
Upon a fresh install of the haskell-platform (via homebrew) (GHC x64 7.6.3) on OSX 10.9.2 I receive the following warnings when I run ghc-pkg check (see below)
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

Warning: haddock-html: /usr/local/Cellar/haskell-platform/2013.2.0.0/share/doc/case-insensitive-1.0.0.1/html doesn't exist or isn't a directory
Per the docs:
ghc-pkg check
Check the consistency of package depenencies and list broken packages.
Accepts the --simple-output flag.
I attempt to run the following command to generate haddock documentation to no avail:
sudo cabal install --reinstall --force-reinstalls --enable-documentation
The command was from a similar question a user had on the haskell mailing list.http://www.haskell.org/pipermail/glasgow-haskell-users/2012-February/021780.html
How do I appease ghc-pkg check and remove these warnings?
CAVEAT: When I say "fresh install" I mean I have installed the Haskell-platform from scratch, and installed globally cabal-1.18.0.3and added cabal's bin directory to my path.
解决方案
Those haddock warnings are annoying, but they don't cause any problems, AFAIK. I think the warnings were fixed in Cabal 1.18. I don't see them any more.
EDIT: OK, so we need to follow kosmikus's suggestion...
mv ~/.cabal ~/.cabal.SAVE
cabal update
This will create the file ~/.cabal/config. You can edit this file if you wish.
Now try building something and see if the problem is gone.
