다른 블로그를 보고(특히 윈도우예제) pip로 인스톨하시는 분들이 있는데,
맥은 파이썬2버전이 원래 깔려있어서 pip3로 설치해야 합니다.
pip로 설치하면 제대로 작동하지 않을 수 있습니다.
파이썬2 셀레니엄 삭제
sudo pip uninstall selenium
파이썬3 셀레니엄 삭제
sudo pip3 uninstall selenium

[MAC/PYTHON] 맥북에 파이썬 PIP 설치하기, command not found: pip
파이썬 설치하면 PIP를 쓸수있다길래 해봤는데 안되네요.
윈도우는 잘 모르겠지만 맥은 파이썬을 설치한 후에 PIP는 별도로 설치해야하나봅니다.
터미널에서 실행하면 다음과 같이 pip따위는 없다는 오류가 발생합니다.
kaudo@MacBookPro ~ % pip
zsh: command not found: pip
