상황

• python3.10이 기본인 ubuntu 22.04에서 python3.9 설치 후 virtualenv로 환경을 분리했다.
• 분리한 환경을 activate하고 평상시처럼 pip3 install -r requirements.txt로 의존성 설치 시도시 아래의 오류가 발생한다.

시도 1: 실패

• sudo apt-get install python3-distutils 이걸 해보라고 해서 설치해보았다.

결과는 동일했다.

시도 2: 성공

• 찾아보다보니 마이너 버전별로disutils가 다르다고 다르다고 한다.

나는 python3.9 사용을 원했기에, sudo apt-get install python3.9-distutils 이렇게 설치했고, 이후 정상적으로 진행가능했따.
