mac下更换镜像安装Homebrew教程

Homebrew是一款包管理工具，目前支持macOS和linux系统。主要有四个部分组成: brew、homebrew-core 、homebrew-cask、homebrew-bottles。

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

如果你等待一段时间之后遇到下面提示，就说明无法访问官方脚本地址：

curl: (7) Failed to connect to raw.githubusercontent.com port 443: Operation timed out

请按照下面「安装说明」中步骤执行。

创建并进入安装目录：

分别安装中科大镜像源的homebrew-core 和 homebrew-cask：

/bin/bash -c "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/install.sh)"

最后看到==> Installation successful!就说明安装成功了。

最最后更新下：

使用官方脚本同样会遇到uninstall地址无法访问问题，可以使用下面脚本：

/bin/bash -c "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/uninstall.sh)"

brew、homebrew/core是必备项目，homebrew/cask、homebrew/bottles按需设置。通过 brew config 命令可以查看相关配置信息。
