为Haskell安装Yesod时出现问题 [英] Problems installing Yesod for Haskell

问题描述

我试图按照本指南安装Haskell和Yesod for Mac 。一切都很顺利，直到最后一步，当我收到此错误消息。我试着手动安装 hfsevebts-0.1.4 ，但它给了我同样的错误。

I'm trying to install Haskell and Yesod for Mac following this guide. Everything goes fine until the last step, when I receive this error message. I've tried to manually install the hfsevebts-0.1.4 but it gives me the same error.

gcc-4.8: error: language objective-c not recognized
gcc-4.8: error: language objective-c not recognized
cabal: Error: some packages failed to install:
fsnotify-0.0.11 depends on hfsevents-0.1.4 which failed to install.
hfsevents-0.1.4 failed during the building phase. The exception was:
ExitFailure 1
yesod-bin-1.2.3.4 depends on hfsevents-0.1.4 which failed to install.

如何安装Yesod？

How shall I proceed in order to install Yesod?

推荐答案

我认为这为我解决了这个问题：

I think this fixed it for me:

   $ brew uninstall gcc48
   $ brew install gcc48 --enable-all-languages

假定默认的gcc48不包含Objective-C。

Presumably the default gcc48 doesn't include Objective-C.
