@dd-jy Thank you for the report! Do you mind to check if this still happens with the latest develop since we are about to release v32? This would be super helpful!
This would be with:

- Create a python 3.7.15 environment with pyenv or global python configuration.
- Get a fresh git clone of scancode
- create a virtualenv locally with `python -m venv .` and then `source bin/activate`
- Install scancode with the command 'pip install -e .'
- Run the scancode 'scancode -v'

@dd-jy the issue comes from this other issue opensanctions/fingerprints#15

Short term you can run this workaround instead: pip install scancode-toolkit fingerprints==1.0.3

@pombredanne
I tested with the latest develop branch and it still happens.
But, the workaround works fine.

@pombredanne when will it be fixed?
