I am trying to install the **owlready2** lib in Ubuntu by following the method below but I face a problem.

* I updated the system and applications
* Installed Python 3 and made it the working version (default)
* Installed pip3
* Used pip and pip3 to install the owlready2 lib

But I faced the below problem which seems to be a problem with the library package:

> 
> error: can't copy './hermit/org/semanticweb/hermiT/hierarchy':
>  doesn't exist or not a regular file"

Does anyone have any ideas how to resolve this?
