我正在尝试在 OSX 10.7.5 上安装 cabal-nirvana，但得到以下输出：

cabal install cabal-nirvana
Resolving dependencies...
Downloading cabal-nirvana-0.2.2...
Configuring cabal-nirvana-0.2.2...
Building cabal-nirvana-0.2.2...
Preprocessing executable 'cabal-nirvana' for cabal-nirvana-0.2.2...
<command line>: cannot satisfy -package-id HTTP-4000.2.3-c26f702c170ca487dfea54c2f3d6d4c0
    (use -v for more information)
cabal: Error: some packages failed to install:
cabal-nirvana-0.2.2 failed during the building phase. The exception was:
ExitFailure 1

有任何想法吗？

如果有帮助，ghc: 7.4.1 cabal-install: 0.14.0

当我进行 ghc-pkg 检查时，我得到以下输出：

WARNING: cache is out of date: /Library/Frameworks/GHC.framework/Versions/7.4.1-    i386/usr/lib/ghc-7.4.1/package.conf.d/package.cache
  use 'ghc-pkg recache' to fix.

没关系......我做了'ghc-pkg recache'和'sudo cabal update cabal-install'，然后我能够毫无问题地安装cabal-nirvana......这里的关键字似乎是'sudo'.. . 哦！

...我所说的“Nevermind”并不是指 Nirvana 专辑 :)
