Macos 在haskell平台2013.2.0.0的Mac OS X上安装时尚haskell时出错

在尝试安装hackage的时尚haskell软件包时，我总是会遇到相同的错误。 安装进行得很顺利，直到安装了导管，而导管几乎无法正确安装

错误消息的结尾：

        17 warnings and 2 errors generated.
        Failed to install conduit-1.0.8

我不是这方面的专家，但我认为这是因为小牛用一个

gcc

半兼容包装器包装的

clang

版本取代了标准的

gcc

。它不时使GHC窒息。您可以通过编辑

/usr/local/lib/ghc-7.6.3/settings

来修复它，以便

“C编译器命令”

入口指向有效的

gcc

例如，我从自制中安装了

gcc

4.8，然后将设置行更改为

 ("C compiler command", "/usr/local/bin/gcc-4.9")

---

此问题可以通过以下解决方法解决

如其他一些答案所述，这是由于gcc
