macos - 在 Mac 上安装 Haskell 软件包

Question

我似乎无法在我的 Mac (10.6.8) 上安装一些 Haskell 软件包。我首先尝试了 Happstack，但失败了，然后我尝试了 Snap。

有时，当我运行 ghci 时，会出现段错误。

其他时候它的工作原理如下:

GHCi, version 7.4.2: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Prelude>

尝试获取 Snap 时:

....
....
....
Loading package vector-0.10.0.1 ... linking ... done.
Loading package zlib-0.5.4.0 ... linking ... done.
Loading package zlib-bindings-0.1.1.3 ... linking ... done.
Loading package zlib-enum-0.2.3 ... linking ... done.
Loading package snap-core-0.9.3.1 ... linking ... done.
Loading package snap-server-0.9.3.3 ... linking ... done.
Loading package directory-tree-0.11.0 ... linking ... done.
cabal: Error: some packages failed to install:
snap-0.11.2 failed during the building phase. The exception was:
ExitFailure 11

我已经见过这个问题几次了，但没有什么能真正解决我的问题。有什么想法吗？

您是否尝试过使用 homebrew ？它为您处理依赖关系。

使用 homebrew，您可以使用 brew 命令安装 ghc 和 cabal-install。

$ brew install ghc cabal-install

安装后，您应该能够运行:

$ ghc
ghc: no input files
Usage: For basic information, try the `--help' option.

以及 Haskell 解释器 ghci:

$ ghci

希望这有帮助!
