如何在Mac OSX上为Haskell 7.6.1安装Haskell cabal工具？ [英] How to install Haskell cabal tool for Haskell 7.6.1 on Mac OSX?

问题描述

我根据本页上的说明在MAC OSX上安装了Haskell。

版本7.6.1
http://www.haskell.org/ghc/download_ghc_7_6_1

然而，它如何安装cabal？

解决方案

从那一页开始：

停止！

对于大多数用户，我们建议安装 Haskell Platform 而不是GHC。目前的Haskell平台版本包括最近的GHC版本以及一些其他工具（如cabal）以及已知可协同工作的更大的一组库。 b

因此，遵循该链接可以获得您想要的结果： Haskell平台是GHC加上所需的软件包和工具，包括Cabal（库）和cabal-install（命令行工具）。由于您使用的是OS X，因此您可以使用 Homebrew 获取GHC和Cabal： brew install ghc cabal-install 。

I installed Haskell on MAC OSX according to the instructions on this page.

Version 7.6.1 http://www.haskell.org/ghc/download_ghc_7_6_1

However, it does not install the cabal tool which I need for installing packages.

How can I install cabal?

解决方案

From the top of that page:

Stop!

For most users, we recommend installing the Haskell Platform instead of GHC. The current Haskell Platform release includes a recent GHC release as well as some other tools (such as cabal), and a larger set of libraries that are known to work together.

So following that link will get you what you want: the Haskell Platform is GHC plus the packages and tools you want, including Cabal (the library) and cabal-install (the command-line tool). Since you're on OS X, you can also use Homebrew to get the GHC and Cabal if you want: brew install ghc cabal-install.
