brew之加速 - 技术 - 我的学习文章

有没有出现这种场景：使用brew install 安装程序，一直卡在brew updating，这可能是使用着默认的github镜像源导致，那么我们就需要将其切换到国内

1.镜像切换（推荐中科大）

1）替换brew.git
cd "$(brew --repo)" git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git //清华 或
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git //中科大 2）替换homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git //中科大 或
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git //清华 3）替换homebrew-cask

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-cask" git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git

4）替换homebrew-bottles: 
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile 
或 
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile source ~/.bash_profile 5）应用生效 brew update -v (查看过程)

2.镜像复原

# 重置brew.git:
$ cd "$(brew --repo)" $ git remote set-url origin https://github.com/Homebrew/brew.git  # 重置homebrew-core.git:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" $ git remote set-url origin https://github.com/Homebrew/homebrew-core.git

3. 问题修复

# 诊断Homebrew的问题:
$ brew doctor
# 重置brew.git设置:
$ cd "$(brew --repo)" $ git fetch
$ git reset --hard origin/master
# homebrew-core.git同理:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" $ git fetch
$ git reset --hard origin/master
# 应用生效:
$ brew update
