[PyQt5] module 'enum' has no attribute 'IntFlag'

Problem: module 'enum' has no attribute 'IntFlag'

PyQt5의 실행파일을 만들기 위한 pyinstaller 인스톨 할 다음과 같은 경고를 확인하였다.

Traceback (most recent call last):

사실 이전에, pip으로 설치해보니, 호환성 문제로 구형 버전의 pyinstaller가 깔렸고, 여차저차 써보니 다음과 같은 에러와 함께 작동 중지가 되었다.

Exception: Cannot find PyQt5 plugin directories

그래서 Exception: Cannot find PyQt5 plugin directories으로 구글링을 하며 열심히 트래킹을 한 결과,

원인은 enum이다. 하지만 패키지 검색하면 정확히는 enum34 이름도 이눔!! 이눔의녀석!!! 내가 지금 만 34살이지...

여튼 문제는 enum34 enum 말고 enum34를, 서른 네살의 이눔을 지워버리자...!
** PyQT5에서 쓰는 enum은 파이썬 기본 모듈인데, 어디선가(?) 깔린 enum34가 이름이 같아 충돌이 일어나는 원인이었던 것으로...

마치 흔히 pandas를 쓸 때 column 이름을 count로 지정하고 df.count로 안불러와 지는 것과 같은 문제... 동명이인의 문제...

Solution

pip uninstall enum34 -y
pip install pyinstaller

끄읕!
