在 macOS Sierra 上安装 Snap 时出现问题
Issue installing Snap on macOS Sierra
我在 macOS Sierra 上安装 Haskell 框架 Snap 时遇到问题。每当我安装它时，我都会收到以下消息：

cabal: Error: some packages failed to install:
configurator-0.3.0.0-6dySPcNCURWFswtMXJvzho failed during the building phase.
The exception was:
ExitFailure 1
snap-1.0.0.2-5CZKyA9EY4oLgkpHYCVfnv depends on snap-1.0.0.2 which failed to
install.
我正在使用通过自制软件 (brew cask install haskell-platform) 和 cabal 版本 2.0.0.2 安装的 Haskell 平台。我尝试使用 sudo 并删除我的 ~/.ghc 文件
这看起来像是 Cabal 2（或潜在的 GHC 8.2）中的错误。参见 https://github.com/haskell/cabal/issues/4728。我建议暂时使用 cabal 1.24 或 Stack 坚持使用 GHC 8.0.2。我是 Stack 的情况，版本无关紧要，因为它将使用 GHC 附带的 Cabal 版本。
完整的 8.2.1 二进制平台构建存在一个刚刚解决的问题：https://mail.haskell.org/pipermail/haskell-cafe/2017-October/127979.html
这很可能就是其中的一个例子。
（另见：GHC cannot find libraries on fresh install of Haskell-Platform）
