ImportError: cannot import name 'LegacySpecifier' from 'packaging.specifiers'

[bvidovic1]

This error appears with pipenv version:

pipenv, version 2022.12.19

. Reason is that after packaging pypi package version 21.3 they removed Legacy Specifier. https://packaging.pypa.io/en/stable/changelog.html#id2

Workaround is to lock packaging dependency in Pipenv file to 21.3:

vistir = "==0.6.1" 
packaging = "==21.3"

vistir is there because of this issue: https://github.com/Madoshakalaka/pipenv-setup/issues/138 .
