brew_install.rb 安装brew的文件_安装本地的.rb文件

 安装brew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

如果上述方法安装不了（被强了）， 就用下面这个文件安装，下载后命名为brew_install.rb

然后再执行

ruby  brew_install.rb

这样就可以安装好。

嫌下载速度慢的，替换国内镜像源

 

# 替换brew.git
cd "$(brew --repo)"
git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
# 替换homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
# 刷新源
brew update

如果脚本停在

==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...

复制代码
出现这个原因是因为源不通，代码来不下来，解决方法就是更换国内镜像源：

手动执行下面这句命令，更换为中科院的镜像：

git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1
复制代码
然后把homebrew-core的镜像地址也设为中科院的国内镜像

cd "$(brew --repo)"
 
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
 
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
 
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
复制代码
执行更新，成功：

brew update
复制代码
最后用这个命令检查无错误：

brew doctor
复制代码
至此HomeBrew就安装完成了。

更改默认源

直接使用 Homebrew 还需要更改默认源。以下是将默认源替换为国内 USTC 源的方法。 如下：

替换核心软件仓库

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
复制代码
替换 cask 软件仓库（提供 macOS 应用和大型二进制文件）

cd "$(brew --repo)"/Library/Taps/caskroom/homebrew-cask
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git
复制代码
替换 Bottles 源（Homebrew 预编译二进制软件包）

bash（默认 shell）用户：

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile
复制代码
zsh 用户：

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc
source ~/.zshrc
复制代码
