맥북 파이썬 SSL 인증 실패 오류 (feat.[SSL: CERTIFICATE_VERIFY_FAILED])

왜 말을 안 듣는거야!!!

그지같은 맥북 (하지만 이쁘죠?)

파이썬 설치하나 하는데도 뭔 인증을 해줘야하는건지

이해가 안간다 (하지만 이쁘죠?)

손 진짜 많이가고 번거로운데 (이쁘니까) 내가 참는다

1) [에러 발생] 파이썬 인증 에러

간만에 OS 싹다 밀고 쓰려니

파이썬이 없네?

파이썬 설치하고 보니 코드가 실행이 안돼

아래와 같은 에러 발생

인증이 안됐댄다

 

2) [에러 해결] 맥의 파이썬은 인증을 받아야한다

Mac OS 싹다 밀고 다시 설치한건 또 처음이라 찾아보니 맥에 설치한 파이썬은 인증을 받아야한다네...

귀찮은 애증의 이쁜 물건... 해결해보자

 

(1) 파이썬 설치 경로로 간다

저기 보이는 'Install Certificates.command'를 실행

 

뭐가 줄줄줄 나오고는 프로세스 완료된다

(정확히는 인증서 깔렸고, ip 버전 낮다고 옹알옹알)

 

 

3) 해결

이제 실행하면 문제없이 잘 된다
