为什么在QRCode扫描项目中使用此库时，我会在Pyzbar模块中遇到错误？

Question

错误是：

Traceback (most recent call last):
  File "P:\Prashant\Python\Attendance\lib\site-packages\pyzbar\zbar_library.py", line 58, in load
    dependencies, libzbar = load_objects(Path(''))

    self._handle = _dlopen(self._name, mode)
FileNotFoundError: Could not find module 'libiconv.dll' (or one of its dependencies). Try using the full path with constructor syntax.

During handling of the above exception, another exception occurred:

我正在使用QR代码扫描在出勤系统上创建项目，然后使用Python来创建它。
我在程序中使用了所有需要的库 喜欢，CV2，numpy，pybase64，pyzbar。

但是我在Pyzbar中遇到了以上错误。

我为这个问题有解决方案。我面临类似的问题，刚刚在计算机上安装了Visual C ++ 64位版本并重新启动。根据您的计算机，在vcredist_x86.exe或vcredist_x64.exe之间进行选择。
