AttributeError: 'module' object has no attribute '_find'

Got the $subject error while starting with python 2.7 and with python 3.7 after adding the utils folder which is not installed by default via pip. Might related to click component (I am using click 7.0 on 2.7 and click 7.1.2 on 3.7) as the traceback includes click entries.

Traceback (most recent call last):

Is this project is dead? Any similar application is there? I would like to use the archive duplicate function which I hope means this application is able to search for duplicates between different archive files content.
