gguridi/iab-tcf

A Python implementation of the IAB consent strings (v1.1 and v2)

iab-tcf's Issues

Inability to use own package with name 'tests' from the root project directory

After installing tcf-iab (0.1.7) I can't use package tests in my framework(in root folder), because it has link to iab-tcf tests

Upgrade bitarray-hardbyte dependency

On later stacks iab-tcf cannot be installed due to its dependency on bitarray-hardbyte==1.5.2
I guess most reasonable would be upgrading this dependency - ideally by a not as strict dependency
