brew之加速

　　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

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-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

4）应用生效
brew update

 

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
