我在macOS Sierra上安装Haskell框架Snap时遇到问题。每当我安装它，我收到以下消息：

我使用的是使用homebrew安装的Haskell平台（ brew cask install haskell -platform ）和cabal版本2.0.0.2。我已经尝试使用sudo并删除我的〜/ .ghc 文件

解决方案

完整的8.2.1二进制平台版本存在一个问题，这个版本刚刚得到解决：

这可能是

I'm having trouble installing the Haskell framework Snap on macOS Sierra. Whenever I install it, I get the following message:

The exception was:

I'm using the Haskell Platform installed using homebrew (brew cask install haskell-platform), and cabal version 2.0.0.2. I have tried using sudo and deleting my ~/.ghc file

解决方案

There was an issue with full 8.2.1 binary platform builds that's just been resolved: https://mail.haskell.org/pipermail/haskell-cafe/2017-October/127979.html

This was likely an instance of that.
