Mac安装geth的记录

使用mac安装geth相对来说简单许多，本文就是对一些教程的整理。随着时间的推移，原来教程里的某些代码可能无法使用，所以本文就综合了几篇教程，完成了Mac安装geth的目的。

安装基础依赖

xcode-select --install
如果提示
xcode-select: error: command line tools are already installed, use “Software Update” to install updates
就是安装过了，跳过这一步，继续下一步。我这里就是已经安装过了。

安装包管理工具

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
这一步安装的是brew工具，有些命令我尝试过不可用，这一行安装命令截止到2022年4月还是可以用的。

安装以太坊和geth

brew update
brew tap ethereum/ethereum
brew install ethereum

测试安装结果

geth --help
安装成功会显示下面信息，这是开头的一部分信息，没有全部列出来。
