Mac OS 10.9.5에서 kombu로 런타임 오류가 발생했습니다.

Question

OS X 10.9.5에서 Python에서 Celery를 사용하려고하면 이상한 오류가 발생합니다. 이것은 이전에 사용되었지만 kombu.five를 가져올 때 C 라이브러리를 사용하지 못했습니다.

나는 (brew install python를 통해 설치) 파이썬 2.7.8와 셀러리와 다시마 (pip install celery를 통해 설치)의 최신 버전을 사용하고 있습니다. 어떤 힌트?

다음

좀 더 출력 관련하는 ctypes입니다 :

여기 brew --config 내 출력

>>> import ctypes, ctypes.util 
>>> CoreServices = ctypes.CDLL(ctypes.util.find_library('CoreServices')) 
>>> print CoreServices 
<CDLL 'None', handle fffffffffffffffe at 10eac1e50>

Answer 1

그것을 발견, 감사 TimSmith! Homebrew Python과 Paraview에서 사용하는 라이브러리 간에는 DYLD_FALLBACK_LIBRARY_PATH 환경 변수가 충돌했습니다.
