在 Mac M1/M2 上安裝 HomeBrew

Homebrew

透過 HomeBrew 安裝 Cocoapods，輸入以下指令

brew install cocoapods

檢查是否安裝成功

pod --version

若出現以下錯誤

("xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun\n") (RuntimeError)

請使用以下指安裝缺少的套件

xcode-select --install

最後即可完成安裝 Cocoapods
