OSError: [WinError 123]

장고 런서버 테스트 중 에러발생.

$ python manage.py runserver

...

OSError: [WinError 123] 파일 이름, 디렉터리 이름 또는 볼륨 레이블 구문이 잘못되었습니다: '<frozen importlib._bootstrap>'

부트스트랩..?
분명 어제까진 이상없었는데..?

구글링 결과.
settings.py > INSTALLED_APPS 에서 ,(콤마)를 누락하면 발생된다고한다.
아 별거아니었네~

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'rest_framework_simplejwt',
    'users',
]

어? 이상 없는데?

그럼 디렉토리 문제인가?
추가하거나 지운것도 없는데..

이거저거 뒤적거리다가 requirements.txt 확인.

석세스? 누락되었었나..?
그럼 어제도 안돌아갔었어야하는거 아닌가..
아무튼 다시 서버를 돌려보자.

$ python manage.py runserver
Watching for file changes with StatReloader

Django version 4.2, using settings 'drf_project.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.

된다!

남들처럼 ,하나 찍는걸로 오류가 해결된건 아니지만..
어쨌든 해결해서 다행이다.
단지 이거 하느라 걸린 시간이 처음부터 다시 한거보다 더 걸렸을 것 같다는게 문제..
근데 pip list가 왜 많아졌을까..?
저게 혹시 다른 문제를 일으키진 않을까..?
그건 다음에 알아보자..
