brew之加速

　　有沒有出現這種場景：使用brew install 安裝程序，一直卡在brew updating，這可能是使用着默認的github鏡像源導致，那么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.鏡像復原

# 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. 問題修復

# 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同理:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
$ git fetch
$ git reset --hard origin/master

# 應用生效:
$ brew update
