그것은 실제 문제처럼 보인다는 당신은 설정 단계에서 libffi을 찾을 수 없다는 메시지 수백을 볼 수 있습니다. libffi가 설치되지 않은 것입니다 , ffi.h 등을 포함하는 C 컴파일러 오류가 발생하는 경우 설치를 수행해야합니다.

이 라이브러리는 Python 라이브러리가 아니라 C 라이브러리로, yum 또는 apt으로 설치할 수 있습니다. 또는 brew 또는 port 또는 무엇이든; 그렇지 않은 경우 다운로드하여 수동으로 설치할 수 있습니다. (IIRC의 경우 ./configure && make install 만 가능하지만 해당 문서를 읽으십시오). 일부 플랫폼에서는 libffi-devel 또는 libffi-dev 또는 libffi-libs 또는 이와 유사한 패키지가 필요할 수도 있습니다.

또한 libffi이 없다는 사실은 CPython 개발 파일이 없다는 것을 의미합니다 (대부분의 플랫폼에서는 libffi에 의존하기 때문에). 이걸 지나쳐 라. 이들은 pythonpython-devel 등 (또는 어쩌면 python27-devel 또는 이와 유사한)에서 별도의 패키지에있을 수 있습니다.

결국 UnicodeError은 무엇입니까? 글쎄, 당신은 분명히 당신의 셋업에 짜증이 난다. 모든 결과물에 âmore_coreâ과 같은 내용이 표시되며, 각 '은 â으로 인쇄됩니다. UTF-8 라틴어 대 모기 베크 냄새가 나지만 확실하지는 않습니다.

어쨌든, 어떤 점에서, 파이썬은 (는 약 0xe2을 불평 점에 유의하고, '\xe2'.decode('latin-1')이 u'â' 임) â 문자가 포함 된 일부 출력 (실제 예외의 가능성이 가장 높은 예외 메시지 중 하나)을 생성하기 위해 노력하고있다. 하지만 그것은 터미널을 감지하지 못했기 때문에 문자열을 ASCII로 인코딩하려고합니다. 물론 실패합니다. 따라서 실제 오류를 숨기는 UnicodeError이 발생합니다. (이것은 2.x 디자인으로 해결하기가 불가능한 것 중 하나이며, 3.x 지점에서 상당히 초기에 수정되었으며 그 이후로 더 개선되었습니다.) 여전히 2.7을 사용하고 있으므로 도움이되지 않습니다.)

'libffi'를 설치하려고했는데 "libffi-3.0.5-3.2.el6.x86_64 패키지가 이미 설치되어 있고 최신 버전"이라고 말합니다. – Nilesh

@Lafada : 좋아요,'libffi-devel' 또는 배포판이 그런 꾸러미를 무엇이라고 부르는지는 제가 다음 단락에서 말했듯이 무엇입니까? 이것이'pkgconfig' 레코드,'.so' 심볼릭 링크, 헤더 파일, 그리고'libffi'에 의존하는 것을 만드는 데 필요한 다른 모든 것들을 얻는 방법입니다. – abarnert

설치 중 .... – Nilesh
