以下是查看和修改 Homebrew 源的详细步骤,适用于需要切换到国内镜像以加速下载的场景:
1. 查看当前 Homebrew 源
bash
# 查看 brew 主仓库地址
git -C "$(brew --repo)" remote get-url origin
# 查看 homebrew-core 仓库地址
git -C "$(brew --repo homebrew/core)" remote get-url origin
# 查看 homebrew-cask 仓库地址(如安装了 cask)
git -C "$(brew --repo homebrew/cask)" remote get-url origin
2. 修改为国内镜像源(以中科大镜像为例)
bash
# 设置 brew 主仓库
git -C "$(brew --repo)" remote set-url origin https://mirrors.ustc.edu.cn/brew.git
# 设置 homebrew-core 仓库
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
# 设置 homebrew-cask 仓库(可选)
git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git
# 刷新缓存
brew update
3. 其他国内镜像源选项
-
清华大学镜像:
bash# brew 主仓库 git -C "$(brew --repo)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git # homebrew-core git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git # homebrew-cask git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git
-
阿里云镜像:
bash# brew 主仓库 git -C "$(brew --repo)" remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git # homebrew-core git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
4. 恢复为官方源
bash
# brew 主仓库
git -C "$(brew --repo)" remote set-url origin https://github.com/Homebrew/brew.git
# homebrew-core
git -C "$(brew --repo homebrew/core)" remote set-url origin https://github.com/Homebrew/homebrew-core.git
# homebrew-cask
git -C "$(brew --repo homebrew/cask)" remote set-url origin https://github.com/Homebrew/homebrew-cask.git
5. 验证修改是否成功
再次运行步骤 1 的命令,确认输出的仓库地址已变更为所选镜像源。
注意事项
-
中科大镜像限制:中科大镜像仅支持 macOS 和 Linux 系统,不支持 Windows。
-
环境变量影响 :如果设置了
HOMEBREW_BREW_GIT_REMOTE
或HOMEBREW_CORE_GIT_REMOTE
环境变量,可能会覆盖手动设置的源。检查并删除这些环境变量:bashunset HOMEBREW_BREW_GIT_REMOTE unset HOMEBREW_CORE_GIT_REMOTE
-
更新问题 :切换镜像后若遇到更新失败,可尝试清除缓存并重新更新:
bashbrew cleanup brew update --force
根据网络情况选择合适的镜像源,国内推荐使用中科大或清华的镜像。
