cabal 安装...失败 - osx - 许多不满意的软件包

Question

更新：运行 ghc-pkg 检查报告：

~: ghc-pkg check
WARNING: cache is out of date: /Library/Frameworks/GHC.framework/Versions/7.0.3i386/usr/lib/ghc-7.0.3/package.conf.d/package.cache
  use 'ghc-pkg recache' to fix.
~: ghc-pkg recache

之后阴谋集团似乎更快乐了！

尝试安装 yesod 但第一次安装失败是：

Cabal --version 的输出：

cabal-install version 0.10.2
using version 1.10.1.0 of the Cabal library

有什么想法吗？

在这种情况下，答案是查看 ghc 包缓存是否是最新的，如果不是，则运行 ghc-pkg recache 。

~: ghc-pkg check
WARNING: cache is out of date: /Library/Frameworks/GHC.framework/Versions/7.0.3i386/usr/lib/ghc7.0.3/package.conf.d/package.cache
  use 'ghc-pkg recache' to fix.
~: ghc-pkg recache

这样做使我能够安装 yesod。
