macOS 安装 Homebrew

我可能就是闲的很，想搞事情，Homebrew的镜像换来换去结果出了很多问题。于是就倒腾了以下，就简单的记录下吧。我不知道其他人有没有遇到过这种情况，反正我是不会把镜像源换来换去了...

下载安装脚本

curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> ~/Desktop/brew_install.rb && vsc ~/Desktop/brew_install.rb

PS. vsc是VScode命令，也可以用其他编辑器打开，比如vim

如果安装了VS code，但没有命令，可以执行以下语句。如果觉得vsc不太适合，也可以换成别的

ln -s /Applications/Visual\ Studio\ Code.app/Contents/Resources/app/bin/code /usr/local/bin/vsc

修改安装脚本

1. 修改上游镜像

   找到这一行语句

   BREW_REPO = "https://github.com/Homebrew/brew".freeze
   

   替换成以下语句

   BREW_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git".freeze
   

   PS. 这里采用的是清华大学的Homebrew上游镜像，当然你也可以使用其他的国内镜像

2. 注释自更新语句

   注释前

   ohai "Downloading and installing Homebrew..."
   Dir.chdir HOMEBREW_REPOSITORY do
     # we do it in four steps to avoid merge errors when reinstalling
     system "git", "init", "-q"
   
     # "git remote add" will fail if the remote is defined in the global config
     system "git", "config", "remote.origin.url", BREW_REPO
     system "git", "config", "remote.origin.fetch", "+refs/heads/*:refs/remotes/origin/*"
   
     # ensure we don't munge line endings on checkout
     system "git", "config", "core.autocrlf", "false"
   
     system "git", "fetch", "origin", "master:refs/remotes/origin/master",
            "--tags", "--force"
   
     system "git", "reset", "--hard", "origin/master"
   
     system "ln", "-sf", "#{HOMEBREW_REPOSITORY}/bin/brew", "#{HOMEBREW_PREFIX}/bin/brew"
   
     system "#{HOMEBREW_PREFIX}/bin/brew", "update", "--force"
   end
   

   注释后

   ohai "Downloading and installing Homebrew..."
   Dir.chdir HOMEBREW_REPOSITORY do
     # we do it in four steps to avoid merge errors when reinstalling
     system "git", "init", "-q"
   
     # "git remote add" will fail if the remote is defined in the global config
     system "git", "config", "remote.origin.url", BREW_REPO
     system "git", "config", "remote.origin.fetch", "+refs/heads/*:refs/remotes/origin/*"
   
     # ensure we don't munge line endings on checkout
     system "git", "config", "core.autocrlf", "false"
   
     system "git", "fetch", "origin", "master:refs/remotes/origin/master",
            "--tags", "--force"
   
     system "git", "reset", "--hard", "origin/master"
   
     system "ln", "-sf", "#{HOMEBREW_REPOSITORY}/bin/brew", "#{HOMEBREW_PREFIX}/bin/brew"
   
     # system "#{HOMEBREW_PREFIX}/bin/brew", "update", "--force"
   end
   

开始安装

/usr/bin/ruby ~/Desktop/brew_install.rb

PS. 由于我已经安装成功，无法上传安装成功后的截图

RUBY

Homebrew对ruby版本有一定的需求，在不满足的情况下会重新下载，那么这里我们手动下载。如果觉得麻烦也可以直接跳过这一步，反正包也不大

cat /usr/local/Homebrew/Library/Homebrew/cmd/vendor-install.sh | grep mavericks.bottle.tar.gz

如果没有对Homebrew安装位置进行修改的话，执行以上命令会得到两个url链接

Homebrew Ruby Download Url

直接用第二个链接去下载，下载完成之后移动到以下目录

mv ~/Downloads/portable-ruby-2.6.3.mavericks.bottle.tar.gz ~/Library/Caches/Homebrew

CORE和CASK

1. 手动同步homebrew/core

   git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git $(brew --repo homebrew/core) --depth 1
   

2. 手动同步homebrew/cask

   git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git $(brew --repo homebrew/cask) --depth 1
   

初始化和更新

brew update --force

验证镜像

git -C $(brew --repo) remote -v
git -C $(brew --repo homebrew/core) remote -v
git -C $(brew --repo homebrew/cask) remote -v

Homebrew镜像验证

Homebrew-bottles 镜像
