我最近重新安装了我的Haskell环境，因为我认为在将Mac OS X更新为Mavericks之后，我已将其恢复到恢复之外。

现在每次运行cabal install cabal-install时，都会出现以下错误。

在谷歌搜索后，我发现了这个：http://www.haskell.org/platform/ghc-clang-wrapper

我跑来为Haskell包装clang，但是仍然会出现上述错误。

正在运行ghc-pkg check

The following packages are broken, either because they have a problem
listed above, or because they depend on a broken package.
Cabal-1.18.1.3

为什么我的Haskell环境如此惊人？我该如何解决？

一种方法是删除本地ghc包缓存：

$ cd  ~/.ghc/  &&  rm -rf  */package.conf.d
$ ghc-pkg --user recache

执行此操作后，再次尝试cabal命令。

$ cabal install package-name

那应该有效。如果没有，请尝试删除cabal个包，然后重复上述步骤：

$ rm -rf  ~/.cabal

如果您仍然遇到问题，系统ghc包缓存可能会引用丢失的包。运行此命令：

$ ghc-pkg --user recache
$ sudo ghc-pkg recache
$ ghc-pkg -v check

最后一个命令应该打印系统缓存。在我的GNU / Linux系统上，它打印出来：

using cache: /home/sudoman/.ghc/x86_64-linux-7.6.3/package.conf.d/package.cache
using cache: /var/lib/ghc/package.conf.d/package.cache

此时，根据经验，我没有为您提供解决方案，但您可能需要考虑删除上面的ghc系统包缓存，然后进行重新缓存;或重新安装ghc / haskell-platform。

问题源于cabal可以跟踪同一个包的多个版本。

运行：

cabal install --reinstall Cabal-1.18.1.3
