노션따라서 필요한 프로그램과 파일을 다 설치 후 이제 마지막으로 flutter docter 를 쳐보니

Xcode가 설치되지 않았다고, CocoaPods 을 설치해야한다고 하는거에요!

그래서 노션에 있는 아래 코드를 입력했더니 설치에 계속 실패합니다 :(

brew install cocoapods
sudo gem install cocoapods

brew install cocoapods

sudo gem install cocoapods

zsh: command not found: brew

Building native extensions. This could take a while...

ERROR:  Error installing cocoapods:
