1. 依赖

git

git安装方法：

下载安装包地址：https://git-scm.com/download/mac

Binary installer

Tim Harper provides an installer for Git. The latest version is 2.27.0, which was released 5 months ago, on 2020-07-22.

2. 准备目录

M1之后，不能放到 /usr/local/bin目录下了。要放到/opt目录下 所以新建/opt目录，cd /opt && sudo chmod -R 777 ./  授权给所有用户所有权限

3. 下载安装脚本

cd /opt && curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh > Homebrew.sh

4. 打开脚本修改安装目录

vim /opt/Homebrew.sh 

将 HOMEBREW_PREFIX的值修改成 HOMEBREW_PREFIX="/opt" 并保存

5. 执行安装命令

cd /opt && /bin/zsh Homebrew.sh 

建议选择腾讯或者是阿里

6 . 配置环境变量

sudo vim /etc/profile 在最后一行添加 export PATH=$PATH:/opt/Homebrew/bin

source /etc/profile 

最好是重启一下电脑，让环境变量永远生效

7. 执行brew -v

/opt/Homebrew/bin/brew: line 11: cd: /usr/local/Homebrew/bin: No such file or directory
