设置全局变量

    echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/wangzhengwei/.zprofile
    eval "$(/opt/homebrew/bin/brew shellenv)"

2.安装ruby
brew install ruby
设置全局变量
export PATH="/opt/homebrew/opt/ruby/bin:$PATH"

全局变量立即生效
source xxxx.zprofile

3.安装cocoapods
sudo gem install -n /usr/local/bin cocoapods
sudo gem install cocoapods(废弃 不知道装哪去了 会报错 pod not found...)

如果报错要升级ruby
brew upgrade ruby
