M1 Mac安装Homebrew卡在Receiving objects 4%，求解决方案

我使用以下命令在M1 Mac上安装Homebrew：

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

但进程始终卡在Receiving objects的4%阶段，日志片段如下：

我已安装Xcode Command Line Tools，且多次重启设备，但问题仍未解决，求可行的解决思路。

• 切换国内镜像源安装
  网络访问GitHub受限是这类问题的核心原因，使用国内镜像脚本可快速解决：

  /bin/bash -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
  

  脚本会引导选择合适的国内源，安装完成后自动配置镜像，避免后续包拉取的网络问题。

• 手动克隆Homebrew仓库

  1. 终止当前安装进程，清理已生成的目录：

     sudo rm -rf /opt/homebrew
     

  2. 克隆国内镜像的brew核心仓库：

     git clone --depth=1 https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git /opt/homebrew
     

  3. 克隆homebrew-core仓库：

     mkdir -p /opt/homebrew/Library/Taps/homebrew/homebrew-core
     git clone --depth=1 https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git /opt/homebrew/Library/Taps/homebrew/homebrew-core
     

  4. 配置shell环境变量（以zsh为例）：

     echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
     eval "$(/opt/homebrew/bin/brew shellenv)"
     

  5. 执行初始化：

     brew update
     

• 排查网络与DNS配置

  • 切换网络环境（如Wi-Fi换手机热点），排除本地网络的GitHub访问限制。
  • 修改DNS为公共服务地址（如8.8.8.8或114.114.114.114），在「系统设置-网络-高级-DNS」中添加并置顶。

• 清理Git缓存后重试官方安装
  清除Git的代理缓存，避免残留的连接配置干扰：

  git config --global --unset http.proxy
  git config --global --unset https.proxy
  rm -rf ~/.gitconfig
  

  之后重新运行官方安装命令。
