Mac 安装brew的正确姿势

你可能尝试了很多办法去安装brew，从一开始的网络超时，到一脸蒙的手动安装，本文教你如何正确安装brew

创建Homebrew目录

打开你的终端执行下面的命令，进行创建Homebrew

sudo mkdir /usr/local/Homebrew

同步brew.git库

sudo git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git /usr/local/Homebrew

添加环境变量

sudo ln -s /usr/local/Homebrew/bin/brew /usr/local/bin/brew

同步core库

sudo mkdir -p /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core

sudo git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core

同步cask

sudo mkdir -p /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask
sudo git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask

提权

sudo chown -R $(whoami) /usr/local/Cellar
sudo chown -R $(whoami) /usr/local/Homebrew

查看版本号

brew -v

更换镜像源

此时你安装东西的话，还是会感受到超时的力量，所以我们需要更换国内镜像源

替换homebrew默认源

cd "$(brew --repo)"

git remote set-url origin git://mirrors.ustc.edu.cn/brew.git

bash用户：

echo ‘export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles‘ >> ~/.bash_profile

source ~/.bash_profile   #刷新

zsh用户

echo ‘export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles‘ >> ~/.zshrc

source ~/.zshrc     #刷新

记得要更新

brew update
