파이썬 pip 명령 에러 메시지 - ModuleNotFoundError: No module named 'pip'

 

pip 명령 에러 메시지 - No module named 'pip'

pip 명령 오류

가상환경에서 잘 사용하던 pip 명령이 업그레이드 이후 가상환경에서 python.exe -m pip install --upgrade pip가 아닌 pip install --upgrade pip 명령으로 업그레이드를 했는데, 이 명령에 어떤 문제가 있었던 건지 pandas 설치를 했는데 ModuleNotFoundError: No module named 'pip' 메시지가 계속 발생하였다.

 

pip 버전을 확인했으나 동일한 에러 메시지가 발생함

(venv) D:\Ex_noviceCoding>pip --version
Traceback (most recent call last):

구글에서 원인을 찾아보니, 
pip install --upgrade pip 명령을 수행한 후 나타나는 현상이고, pip 업그레이드 명령 시 pip 패키지를 삭제하고 다시 설치하는 과정에서 제대로 되지 않아서 발생한다고....
아래처럼 python -m ensurepip 명령으로 해결했다.
