파이썬 용 QR 코드 디코더 라이브러리

Question

파이썬에서 QR 코드를 인코딩하고 디코딩하는 응용 프로그램을 빌드하려고합니다. 나는 인코더와 함께 성공했지만 파이썬에서 디코딩 할 라이브러리 (그러나 zbar)를 찾지 못했습니다. Windows 7 시스템에서 Python 2.7을 사용하고 있습니다.

zbar을 설치할 수 없습니다. 라이브러리에 필요한 종속성 모듈을 설치했는데 심지어 설치하려고 할 때마다 많은 오류가 발생합니다. zbar.h 및 zbarmodule.c에 너무 많은 구문 오류가 있습니다. 나는 그 문제가 무엇인지에 대해 왜 우둔한지를 이해하지 못한다. zbar

를 설치하는 동안

나는 다음과 같은 오류를 얻을

사람이 zbar 설치를 도와 또는 나에게 내가 QR 코드를 디코딩 할 수있는 라이브러리를받을 수 있습니까?

Answer 1

pyqrcode은 QR 코드 인코딩 및 디코딩을 지원합니다.

다른 사람이 언급 한 것처럼 zbar와 관련하여 오류 메시지를 알지 못하면서도 도움이되지 않습니다.

Windows 바이너리 패키지 또는 소스에서 zbar를 설치 했습니까?

zbar 그것은 2.5 및 2.6 사용할 수 here위한 파이썬 모듈 바이너리를 가지고, here 사용할 수있는 미리 만들어진 윈도우 바이너리 패키지가있다. 이 zbar Installation Instructions

은 다음과 같습니다 소스에서 zbar 파이썬 모듈을 설치하기 위의 링크를 기반으로 수행해야하는 단계의 요약을 볼 통해 zbar 설치에 대해서는

.

2. 변수 윈도우 경로에 MinGW
3. Zbar \ 빈과는 MinGW \ 빈 (바이너리 설치 디렉토리)를 추가 설치
4. (이진 here 바람직) zbar를 설치 Zbar 파이썬 모듈을 다운로드 source를 here에서 찾아서 임시 폴더에 압축을 풉니 다.

5. 사용자 정의 zbar 포함 및 라이브러리 경로를 사용하도록 setup.py 스크립트를 수정하십시오. 수정 사용

   library_dirs=["""zbarlibdirectory"""], 
       include_dirs=[get_config_vars('INCLUDEDIR'), 
           get_config_vars('INCLUDEPY'), 
           """zbarincludedirectory"""] 
   

   zbarlibdirectory이 C:\zbar\lib 및 zbarincludedirectory 같은 것입니다

   뭔가

6. zbar 파이썬 모듈을 설치 C:\zbar\include 같은 :

   3 가 확장 호출에 다음과 같은 매개 변수를 추가 줄을 from distutils.sysconfig import get_config_vars 추가 설정.평

   python setup.py build --compiler=mingw32는 Windows7에 설치 pyqrcode에 관해서는

   python setup.py install

, 정말 아직하지 않은 있지만, 먼저 모든 종속성을 설치, 단지 관련 제목 아래 소스 지침을 믿는다 그런 다음 make를 실행하고 MinGW에서 nmake 또는 make를 사용하여 설치하십시오.
