Haskell 堆栈设置 - 无法识别 CPP 程序
Haskell Stack Setup - Can't Recognize CPP Program
我正在学习 Udemy Haskell 课程，其中有一次显示我可以使用 Stack 选项下载 Haskell。当我 运行 遇到问题时，我已经配置了我的 $PATH 和 运行 堆栈设置。

@n.m 评论 link 引导我找到一个问题的答案，建议我检查我的 xCode 列出的开发人员命令行工具版本。原来我的版本没问题，但后来我确实在 .stack/programs/x86_64-osx/ghc-8.0.2.temp/ghc-8.0.2/config.log 中找到了这一行，这让我找到了问题的解决方案。
