막상 import하면 no module 에러가 발생하는 것이죠

이와 관련해서 stack overflow 등 다양한 사례를 살펴보았지만, 유의하게 해결하진 못하였습니다.

짐작해보면, python 내부에서 여러 버전이 충돌해서 생긴 오류인듯 했는데, 이를 해결하려면 초기화를 진행하고 다시 설치하는 방법 뿐이었습니다.

 

따라서 제가 시도한 방법은 가상환경입니다.

2021.11.15 - [python] - 가상환경 만들기 (Mac)

가상환경 만들기 (Mac)

과거에 포스트한 자료를 바탕으로 새롭게 시도해보았습니다.

 

해당 폴더에 접근한 후 virtualenv를 설치하고 soruce bin/acivate한 후에 가상환경을 시행하였습니다.

 

그리고 나서

이렇게 yfinance를 터미널에서 설치한 결과,

다행히 이상없이 시행된 것을 확인할 수 있었습니다.
