기본 python 버전 변경

which 명령을 통해 python3.11 설치된 경로를 확인

which python3.11
/opt/homebrew/bin/python3.11

변경하고 싶은 버전의 Python 경로를 기본 Python 경로에 링크 걸기

# python 기본 명령어 링크생성
sudo ln -s -f /usr/local/bin/python3.11 /usr/local/bin/python

# pip 기본 명령어 링크생성
sudo ln -s -f /usr/local/bin/pip3 /usr/local/bin/pip

경로가 /opt/homebrew/bin 이면 아래와 같이 링크 걸기

# python 기본 명령어 링크생성
sudo ln -s -f /opt/homebrew/bin/python3.11 /opt/homebrew/bin/python

# pip 기본 명령어 링크생성
sudo ln -s -f /usr/local/bin/pip3 /usr/local/bin/pip

변경된 Python 버전 확인

python --version
