请帮帮忙。

最后，我是这样做的：

• 用sudo /Library/Haskell/bin/uninstall-hs (https://stackoverflow.com/a/6996284/1749901)卸载整个平台
• 然后在本教程之后，首先通过brew install apple-gcc42安装apple-gcc42 42。
• 然后链接到brew link apple-gcc42
• 通过brew install haskell-platform安装平台
• cabal update
• cabal install cabal-install
• 添加到PATH $HOME/.cabal/bin中(而不是通过这里通过PKG安装程序安装平台的情况下的$HOME/Library/Haskell/bin，这显然是因为brew的配置略有不同)。
• source ~/.bash_profile，然后重新启动终端，因此which cabal指向<HOME>/.cabal/bin/cabal，cabal --version显示1.18 (而不是1.16)。
• cabal install happy。此时，我再次重新启动终端，因为which happy指向本地更新(1.19.2)版本，但happy --version显示了1.16.x。
• cabal install type-eq -- 第一次继承了！
• 最后，cabal install fay fay-base -成功了！ 安装fay-0.18.1.3安装fay-基本-0.18.0.0

呼！谢谢大家！

Answer 2

这是关于小牛的一个已知的预处理问题。寻找这里的解决方案。

这看起来像是预处理器问题的原因是：

1. 错误消息中提到的行包含CPP宏。
2. 关于小牛队，CPP有一个已知的问题
3. 这个包在Linux上使用GHC 7.6.3 (看起来也像您正在使用的版本)编译得很好

Answer 3

您所需要做的就是将安装目录添加到您的路径！只需将此添加到您的.bash_profile:export PATH="$HOME/Library/Haskell/bin:$PATH“

导出PATH="$HOME/Library/Haskell/bin:$PATH“

我正要卸载整个平台，但后来我发现这个在小牛身上很管用。
