安装brew
/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
升级ruby版本，否则安装cocoapods会报错
brew upgrade ruby
加入环境变量，否则ruby -v版本还是老的
echo 'export PATH="/opt/homebrew/opt/ruby@3.2/bin:$PATH"' >> ~/.zshrc source ～/.zshrc
安装cocoapods
sudo gem install -n /usr/local/bin cocoapods
sudo gem install -n /usr/local/bin cocoapods-binary
