처음에 아래의 포스트를 참고하여 brew로 재설치했다. 성공했지만.. 똑같이 gem으로 설치시에는 동일한 에러가 나서 찝찝했다..

Mac에서 CocoaPods설치중 에러해결

좀더 구글링 하다가 다음 포스트를 찾았다. 에러로그에 나온 모듈들을 설치하면 되는데, 이럴 경우 또 어떤 에러가 나올지 모른다.

Ruby를 최신 버전으로 업데이트 했다.

sudo gem install cocoa-pods 에러나서 안될 때

$ curl -L https://get.rvm.io | bash -s stable
$ source /Users/yjkim/.rvm/scripts/rvm
$ rvm install ruby

$ sudo gem install cocoapods

install 성공!!!
