In linux set environment variable $PYTHONPATH and works well.
But in Windows, After setting environment variable PYTHONPATH and rebooting,it didn't work. Especially in PyCharm terminal.

Answer 1

If your question is specific to PyCharm, I recommend either installing the package into the virtual environment / interpreter you're using for the project from File - Settings - Project: name - Project Interpreter or adding the library to your project and setting the folder to be recognised as a source folder by PyCharm.

Right-click the library folder, then select Mark Directory as - Sources Root
