发现一段错误提示Error: Can‘t find Python executable “python“, you can set the PYTHON env variable,这提示貌也很明显，告诉我们没有python，我在终端检查了一下果然没有。
我记得macos是自带python2.7的，于是我查阅了一下资料，发现Moterey这个版本的操作系统移出了python,需要自己去安装。好吧，认命，我装。
于是我开始使用homebrew安装python3.X。
1 # 命令大概是这样子 2 brew install python3 3 brew link python3
细心的我观察到报错时调用的是’python’命令,于是在.bash_profile中增加了别名配置
1 alias python3='/usr/bin/python3' 2 alias python=python3 3 alias python2=python3
执行brew时报错zsh: command not found: brew
需要安装brew
命令安装
/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
1.运行命令，输入序列号时 直接回车
2.输入大写字母：Y
3.输入mac密码，运行脚本
4.等待安装完成即可（若报错看下文）
若出现报错（不报错则跳过）
报错解决：点击下载插件(https://sourceforge.net/projects/git-osx-installer/)
此软件安装完成之后，再次重新执行安装brew命令
最后 输入命令，查看版本
输入brew -v
能看到版本说明安装成功就可以继续使用brew去安装其他东西
