3줄 요약
- 콘솔창에서 가상환경을 활성화 한다.
- conda install 패키지를 시도한다.
- pip install 패키지를 시도한다.
개발 환경
- Anaconda 4.10.1
- Pycharm 2021.1
Anaconda와 Pycharm을 이용해서 파이썬 웹개발을 시작했다. 플라스크가 가볍고 간편하다고 해서 패키지를 설치했고, ORM을 위해서 Flask-Migrate을 설치하려고 했다. 그런데 Pycharm에서 조회가 안된다.
다른 패키지들은 조회만 하면 설치할 수 있었는데, 이건 왜 안되는걸까? 검색해 보니 콘솔창에서 가상환경을 활성화하고 conda install을 해보라고 한다. 이것도 안되면 pip install. 둘의 차이점은 뭘까? 궁금하지만, 일단 따라해 보자.
먼저 conda install을 해봤다.
(base) C:\Users\race>conda activate realestateweb
(realestateweb) C:\Users\race>conda install Flask-Migrate

왜 못찾을까? anaconda 사이트에서는 조회가 되던데, 안되는 이유를 모르겠다. 일단 진도를 나가야 하니, pip install 실행!

(realestateweb) C:\Users\race>pip로 하니 잘 된다. Pycharm에서도 flask-migrate가 조회되는 걸 확인할 수 있다.
패키지들을 보면 flask-migrate만 Latest version이 없다. 추측컨대 패키지 관리하는 어디에선가 누락된 것이 아닌가 싶다.
