파이썬 크롤러) 파이썬 코딩을 위해 pip로 pandas 등 모듈을 깔 때 주의점 !

왜 자꾸 invalid syntaxError가 뜰까!

라고 하는 분이 있다면...

나와 같은 파이썬 초보일 가능성이 :-).....

pip로 모듈 설치 시 자꾸 까먹는 나의 실수는,

파이썬을 켜놓고 pip3 install 모듈이름을 친다는 것이다 !

파이썬에서 신나게 코딩 연습을 하고 있다가

새로운 모듈을 import해야 한다면,

반드시 exit()으로 나와서

pip3 install pandas 를 쳐주세요 ~ (pip버전이 3.0이전 버전이면 pip만 쳐도 됨)

그리고 관리자실행권한이 필요할 경우에는 맨 앞에 sudo를 붙여서

sudo pip3 install pandas라고 쳐주세요 ~!!

SyntaxError: invalid syntax

>>> sudo pip3 install pandas

  File "<stdin>", line 1

    sudo pip3 install pandas

            ^

SyntaxError: invalid syntax
