[Trouble Shooting] pip install mysqlclient

가끔 새로운 환경에서 MySQL 관련 파이썬 패키지를 다운받을 때 mysqlclient 가져올 때 쯤에 아래와 같은 에러가 발생한다.

Collecting mysqlclient==2.1.1 (from -r requirements.txt (line 38))

  note: This error originates from a subprocess, and is likely not a problem with pip.

찾아보니 해당 패키지 빌드를 위한 파이썬 패키지가 없어서 생긴 오류인듯 하다 !
아래 명령어를 통해 관련 패키지 설치 후, 다시 mysqlclient를 설치하면 된다.

sudo apt-get install python3-dev default-libmysqlclient-dev build-essential
