AttributeError: module 'setuptools.build_meta' has no attribute '__legacy__' #1694
Description
I'm trying to install project I'm working on using pip3 install -e "file:///home/vagrant/devel", but everytime I end up with:
$> pip3 install -e "file:///home/vagrant/devel"

Maybe I'm just doing something wrong, but this worked few days ago.
