Mac切换清华镜像决绝brew update无反应,更新慢解决办法

Mac中使用brew update太慢，就算翻墙也非常慢；主要是资源访问太慢，这种情况我们可以更换国内的源镜像提升速度。

一、替换brew默认源

1、方法一

# 替换brew.git
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

# 替换homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

2、方法二

# brew 程序本身，Homebrew/Linuxbrew 相同
git -C "$(brew --repo)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

# 以下针对 mac OS 系统上的 Homebrew
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git
git -C "$(brew --repo homebrew/cask-fonts)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-fonts.git
git -C "$(brew --repo homebrew/cask-drivers)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-drivers.git

# 以下针对 Linux 系统上的 Linuxbrew
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/linuxbrew-core.git

# 更换后测试工作是否正常
brew update

二、执行更新

最后我们使用brew update更新一下当前brew版本：

# 更新并显示进度
brew update --verbose

这样即可快速更新了，测试发现使用清华镜像速度比中科大的快。

三、如何复原到默认设置。

# brew 程序本身，Homebrew/Linuxbrew 相同
git -C "$(brew --repo)" remote set-url origin https://github.com/Homebrew/brew.git

# 以下针对 mac OS 系统上的 Homebrew
git -C "$(brew --repo homebrew/core)" remote set-url origin https://github.com/Homebrew/homebrew-core.git
git -C "$(brew --repo homebrew/cask)" remote set-url origin https://github.com/Homebrew/homebrew-cask.git
git -C "$(brew --repo homebrew/cask-fonts)" remote set-url origin https://github.com/Homebrew/homebrew-cask-fonts.git
git -C "$(brew --repo homebrew/cask-drivers)" remote set-url origin https://github.com/Homebrew/homebrew-cask-drivers.git

# 以下针对 Linux 系统上的 Linuxbrew
git -C "$(brew --repo homebrew/core)" remote set-url origin https://github.com/Homebrew/linuxbrew-core.git

# 更换后测试工作是否正常
brew update

四、安装 Linuxbrew 时使用 tuna 镜像 (可用 sudo)

0. 安装 git
1. 下载 https://raw.githubusercontent.com/Linuxbrew/install/master/install-ruby
2. 将其中 https://homebrew.bintray.com/bottles-portable-ruby/ 换为 https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles/bottles-portable-ruby/
3. 运行 ./install-ruby 安装 portable ruby
4. export PATH=/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/vendor/portable-ruby/current/bin:$PATH # ==> Add Ruby to your PATH
5. 下载 https://raw.githubusercontent.com/Linuxbrew/install/master/install
6. 将其中 https://github.com/Homebrew/brew 换为 https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
7. 运行 ./install 安装 brew
8. 执行到 “==> Tapping homebrew/core” 时 Ctrl-C
9. export PATH=/home/linuxbrew/.linuxbrew/Homebrew/bin:$PATH # 将 brew 添加到 PATH
10. git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/linuxbrew-core.git "$(brew --repo homebrew/core)"
11. 再次运行 ./install 即可到达安装成功结果
