주요 오류 포인트는 위와 같다.

이를 해결 하기 위해 필요 내용 설치가 진행되어야 하다.

해결 방법

sudo apt update

먼저, update부터 해준다.

sudo apt install default-libmysqlclient-dev pkg-config -y

apt install을 통해 해당 내용 설치. 나는 가상 환경에서 python을 구동중이기에 sudo 없이 입력하였다.

pip install mysqlclient

다음, 오류를 냈던 패키지를 다시 설치한다.

정상 설치가 이루어지면 끝.

하지만, 매끄럽게 진행되지 않고 또 다른 오류가 나타났다.

sudo apt-get -y install gcc

gcc 를 인스톨한다.

pip install mysqlclient

다시, mysqlclient를 인스톨한다.

이제서야 설치 성공 메시지를 볼 수 있었다.

나의 경우 이렇게 진행하여 해결하였다.
