stock.get_market_ohlcv('20220924', '20240223', '032800') # 판타지오 032800
위 코드 실행 시 'OverflowError: Python int too large to convert to C long 오류가 발생합니다.
특이한 점은 데이터 조회 일자에 따라 오류가 발생하기도 하고 정상 동작하기도 합니다.
금일 실행 기준으로,
- 20220924 이전의 데이터에 대해 조회하면 에러가 발생합니다.
- stock.get_market_ohlcv('20220925', '20240223', '032800') 이런 식으로 20220925 이후의 날짜에 대해 조회하면 정상 동작합니다.
코드 실행 환경은 아래와 같습니다.
- 윈도우 10
- anaconda 가상 환경
- 가상 환경 파이썬 버전 3.9.19
해결법을 찾지 못하여 문의 드립니다.

모듈 버전을 확인해 주세요.
import pykrx
print(pykrx.__version__)
현재 최신은 1.0.46 입니다. 과거 버전이라면 업데이트 해 주시구요.
pip install -U pykrx
