Pyinstaller在windows上使用pyscard失败

Question

我试图在一个使用pyscard的简单脚本上使用pyinstaller。

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')

这在Ubuntu上是可以的，但是在Windows7和Windows10机器上失败。在两个版本的窗口上，失败都是相同的，下面是Windows7上的屏幕输出：

[7924] Failed to execute script testpyscard

注意: pyinstaller的可选参数没有任何区别，我尝试了8种组合，包括和不带--onefile，-隐藏-导入和--双赢的私有程序集。在上，只使用脚本的名称和-onefile调用。

注2:在Windows7机器上，Python3.6-32也有同样的问题。我卸载了机器上可以找到的所有python东西，并重新安装了Python3.6x86-64和匹配的pyscard (使用https://ci.appveyor.com/project/LudovicRousseau/pyscard中的dist\pyscard-1.9.6.win- and 64-py3.6.msi)

如果能帮助理解或解决这个问题，我将不胜感激，我甚至不知道问题是否与我的安装程序或Pyinstaller或Pyscard有关:-S

Answer 1

我在Windows 7和Windows 10上也有同样的问题，我认为问题的出现是因为swig_import_helper函数在scard.py中的运行时导入。因此，我在我的PyInstaller选项中添加了以下内容：

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

这解决了我在Windows 7和Windows 10下的问题。

我的测试环境：

• Windows 7 64位
• Python 3.6 32位
• 化粪池1.9.7
• PyInstaller 3.3.1
