   : colorcorrect 라이브러리 설치시 우분투, windows에서는 문제가 없는데 mac 에서만 pip 설치가 안됨.

[ 해결과정 ] 솔루션을 찾아보니 xcode가 10으로 업그레드 하면서 libstdc++.tbd, libstdc++.6.0.9.tbd  등이 libc++로 변경된 이유라 함

  1) xcode9에서 해당 파일을 찾아 xcode10 에 복사

  2) 다음 사이트 참조 : https://medium.com/@devfallingstar/konlpy-%EC%84%A4%EC%B9%98-macos%EC%97%90%EC%84%9C-konlpy%EC%84%A4%EC%B9%98-%EC%8B%9C-%EC%98%A4%EB%A5%98-93c1675875ef
