Ok thanks a lot! I merged your PR, and also converted all paths to string in the config.py module.

@gnebbia please don't

I have tested.

If you str dir file.
when you kb erase then will cause the str can not mkdir problem.
You can test.

Sorry what should I test? in kb erase, no directory is created with mkdir... can you be more specific ?

@gnebbia
If you covert all to str, you will find this problem

Maybe only covert these two red square?

Ok thanks a lot for your help! I think the last commit solved everything, by converting the str back to path when directory creation is required.
Can you confirm that?
Please do a pip uninstall kb and then a pip install . # there is a dot
within the kb directory after having pulled the last commits.

@gnebbia Cool, I think it works perfectly.

P.S.
Thank you for your wonderful repo, that's what I am looking for quite a long time.

Well thanks to you @yihong0618 ! If you didn't warn me about this, I never would have found the bug!

Thanks for your support and appreciation!
P.S.: Feel free to fork the project or implement new features as pull requests!
