brew之加速 - 技術 - 我的學習文章

有沒有齣現這種場景：使用brew install 安裝程序，一直卡在brew updating，這可能是使用著默認的github鏡像源導緻，那麽我們就需要將其切換到國內

1.鏡像切換（推薦中科大）

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

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

4）替換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）應用生效 brew update -v (查看過程)

2.鏡像複原

# 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. 問題修複

# 診斷Homebrew的問題:
$ brew doctor
# 重置brew.git設置:
$ cd "$(brew --repo)" $ git fetch
$ git reset --hard origin/master
# homebrew-core.git衕理:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" $ git fetch
$ git reset --hard origin/master
# 應用生效:
$ brew update
