Hello,

Thanks for your inquiry.
Kindly note that "SkiaSharp" is a dependency library for our Spire.PDF for Python, and our Spire Python products requires the C++ environment. Your error is likely due to a missing 'libSkiaSharp.dll' file. You can check if the file is missing from the dependent installation path("yourPath\python3.9\Lib\site-packages\spire\pdf\lib\libSkiaSharp.dll"). If not, we recommend uninstalling the Spire.Pdf and then reinstalling it again. If the problem still exists. Please provide us with your operating environment and your Python version for investigation. Thank you in advance.

Sincerely,
Amin
