Pyinstaller + opencv打包在部分机器上报错——问题解决

解决方案

在py文件中加入

    import ctypes

    try:

        dll=os.path.join(os.getcwd(),"opencv_ffmpeg343.dll")

        temp=ctypes.windll.LoadLibrary(dll)

        print(f"LoadLibrary {dll}")

    except:

        print("error")

        pass

得新打包

将opencv_ffmpeg343.dll 放到exe所在文件夹

将 api-ms-win-downlevel-shlwapi-l1-1-0.dll 放到 c:\windows\System32

将：api-ms-win-downlevel-shlwapi-l1-1-0.dll 放到C:\Windows\SysWOW64
