最近换电脑了，需要安装homebrew，结果发现访问不了github，导致安装失败，报错信息如下：

curl: (7) Failed to connect to raw.githubusercontent.com port 443 after 1 ms: Couldn't connect to server

解决方法

使用国内的镜像源可以安装成功：

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

执行后按照提示确认即可，一路丝滑到底，还顺便帮你设置了国内的下载源。

git version 2.39.3 (Apple Git-146)开始执行Homebrew自动安装程序[cunkai.wang@foxmail.com]['2024-11-19 16:24:22']['14.3']https://zhuanlan.zhihu.com/p/111014448请选择下列一个 数字编号 后回车
（这里只是下载brew，随意选。国内下载源有5种稍后让你选择配置）1、通过清华大学下载brew
2、通过Gitee下载brew
3、！我已经安装brew，跳过克隆，直接带我去配置国内下载源
4、不克隆brew，只把仓库地址设置成Gitee
5、不克隆brew，只把仓库地址设置成清华大学请输入序号: 1你选择了清华大学brew本体下载源Mac os设置开机密码方法：(设置开机密码：在左上角苹果图标->系统偏好设置->用户与群组->更改密码)(如果提示This incident will be reported. 在用户与群组中查看是否管理员)
