Я работаю над Mac OSX 10.13.6 и пытаюсь построить считыватель штрих-кода, используя python3. К сожалению, я даже не могу импортировать модуль декодирования в пакет pyzbar. Я попытался установить zbar, libzbar0, zbarlight и т. Д., И все попытки потерпели неудачу
Вот мои успешные установки
$ pip3 install pyzbar
Requirement already satisfied: pyzbar in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (0.1.8)
$ pip3 install opencv-python
Requirement already satisfied: opencv-python in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (4.1.1.26)
Requirement already satisfied: numpy>=1.14.5 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from opencv-python) (1.16.2)
Вот сообщение об ошибке при попыткеиспользовать мой успешно установленный пакет pyzbar для импорта функции decode, несмотря на то, что я знаю, что pyzbar имеет функцию декодирования:
>>> from pyzbar.pyzbar import decode

Когда я пытался установить zbar, это произошло:
$ pip3 install zbar

Итак, перейдите к https://pypi.org/project/pyzbar/ и прочитайте, что «DLL-библиотеки zbar включены в колеса Windows Python. В других операционных системах вам потребуется установить общую библиотеку zbar. "Затем сайт дает возможность использовать brew install zbar или pip install pyzbar.
Поскольку я не хочу устанавливать homebrew, я использовал pip install pyzbar.
Это не помогло. Любой совет, как заставить это работать?
