Pyinstaller не работает с Pyscard на Windows

Question

Я пытаюсь использовать pyinstaller на простой скрипт, который использует pyscard.

from smartcard.Exceptions import NoCardException
from smartcard.System import readers
from smartcard.util import toHexString

for reader in readers():
    try:
        connection = reader.createConnection()
        connection.connect()
        print(reader, toHexString(connection.getATR()))
    except NoCardException:
        print(reader, 'no card inserted')

Это нормально в Ubuntu, но не работает на Windows7 и Windows10. Ошибка одинакова в обеих версиях Windows, здесь вывод экрана на Windows7:

[7924] Failed to execute script testpyscard

Примечание: необязательные аргументы для pyinstaller не имеют никакого значения, я попробовал 8 комбинаций с --onefile и --hidden-import и --win-private-сборки. В Ubuntu pyinstaller вызывался просто с именем скрипта и --onefile.

Примечание 2: у меня была та же проблема с Python3.6-32 на компьютере с Windows7. Я удалил все содержимое Python, которое смог найти на компьютере, и заново установил Python3.6 x86-64 и соответствующую ему карту (используя dist\pyscard-1.9.6.win-amd64-py3.6.msi из https://ci.appveyor.com/project/LudovicRousseau/pyscard)

Любая помощь, чтобы понять или исправить проблему, будет принята с благодарностью, я даже не знаю, связана ли проблема с моей установкой или Pyinstaller или Pyscard:-S

Answer 1

У меня была та же проблема в Windows 7 и Windows 10. Я думаю, что проблема возникает из-за импорта во время выполнения в функции swig_import_helper в scard.py. Поэтому я добавил следующие параметры в мой PyInstaller:

--add-data "path_to_python\\Python36-32\\Lib\\site-packages\\smartcard\\scard\\_scard.cp36-win32.pyd;.\\smartcard\\scard\\"

Это исправило проблему для меня как под Windows 7, так и под Windows 10.

Моя среда тестирования:

• Windows 7 64 бит
• Python 3.6 32 бит
• Пискарта 1.9.7
• PyInstaller 3.3.1
