django 설치 진짜 하..

프로그래머스에서 장고 설치를 배웟는데, 너무 어려웠다..
일단 https://velog.io/@soohun9909/m1-django-%EC%84%A4%EC%B9%98%EA%B0%80%EC%9D%B4%EB%93%9C

이 분의 도움을 받아 django를 설치하고 , 안돼서 재부팅했더니 됐다..ㅎ
그리고 python도 뭐가 오류가 떠서 찾아봤더니 3.11 설치하면 된대서 했고,
python3로만 실행돼서 그것도 다시 python으로 되게 설정하고
그리고 나서 다시 프로그래머스에서 나온대로 가상환경을 설정했더니
이제django-admin startproject mysite은 작동을 했다.
그런데 다음 문제가 또 생겼다.

python manage.py runserver

이게 안되는것이다.
왜그런가 나중에 봤더니 일단 cd로 mysite에 들어갔는데
이게 mysite 안에 mysite 파일이 또있어서
어떤 mysite로 들어갔는지 확인을 해봤어야되는 것이다..
처음에 그걸 몰랐어서 다시 삭제하고 다시 처음부터
django-projects폴더를 만들고
djano-venv를
python -m venv djano-venv
로 만들어주고 뭘 했는데..

ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

이와 같은 오류가 떠서

안될때마다 pip install django를 남발했다...ㅎ
그리고 mysite를 생성하고 드디어 cd 경로를 확인 한 뒤,

python manage.py runserver
를 했떠니 잘됐다..감격
아래는 .. 고군분투한 흔적.. 트롤짓을 많이했다..

우여곡절 끝에 !!!끝!!
이걸로 얻은게 많다...

파이썬도 가상환경에 있는 파이썬을 가져와서 vscode에서 써야된다고 한다..
스터디원분이 알려주셨다..ㅠㅠ감사합니다
