Intro

Thanks to GFW, it is extremely hard for Chinese people to get access to package resources on the Internet. After suffering, I managed to deploy Haskell development environment on my Mac.

感谢墙,我们国内人在访问外网资源上体验到了无与伦比的体验。我费了九牛二虎之力在Mac里安装上了Haskell开发环境,特此记录。

Steps

1. Install the Homebrew

安装Homebrew包管理器,如果没有的话...

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Homebrew supports breakpoint continuingly, which is important in a bad network condition.

这货能支持断点续传,尤其适合网络不稳定的地方。

2. Change Homebrew's package mirror

git -C "$(brew --repo)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git

3. Install with homebrew

brew install ghc
brew install cabal-install
brew install haskell-stack

They are Haskell Compiler, package management and integration tools.
这仨分别是Haskell编译器,和俩包管理器之类的东西。

4. Change cabal mirror

At first, run:

cabal update

After the shell generated the ~/.cabal/config configuration file, proceed to the next step.
等你执行了上个命令,就会生成config文件,继续下一步。

Edit ~/.cabal/config,add:
使用vim编辑之:

repository mirrors.tuna.tsinghua.edu.cn
  url: http://mirrors.tuna.tsinghua.edu.cn/hackage

To speed up downloading, we can comment out the official repository.
考虑下把原镜像源也注释掉吧。

5. Change stack mirror

At first, run:

stack update

Then go to ~/.stack

Edit ~/.cabal/config.yaml,add:

package-indices:
  - download-prefix: http://mirrors.tuna.tsinghua.edu.cn/hackage/
    hackage-security:
        keyids:
        - 0a5c7ea47cd1b15f01f5f51a33adda7e655bc0f0b0615baa8e271f4c3351e21d
        - 1ea9ba32c526d1cc91ab5e5bd364ec5e9e8cb67179a471872f6e26f0ae773d42

        - 2c6c3627bd6c982990239487f1abd02e08a02e6cf16edb105a8012d444d870c3
        - 51f0161b906011b52c6613376b1ae937670da69322113a246a09f807c62f6921

        key-threshold: 3 # number of keys required

        # ignore expiration date, see https://github.com/commercialhaskell/stack/pull/4614
        ignore-expiry: no

6. Done

F*** the GFW.
我爱你,墙。
