Can't install vine after upgrading to pip 19.0

[grski]

Basically my pip install fails on this package and throws:

Collecting vine>=1.1.3 (from amqp<3.0,>=2.1.4->kombu<5.0,>=4.2.0->celery==4.2.1->-r requirements/app.txt (line 7))

Dockerfile:

RUN pip3.7 install --upgrade pip && \
        pip3.7 install -r requirements/app.txt --no-cache-dir

Rolling back to 18.1 makes it work correctly, so it's fine for now, but I think it might be worth looking into.

I suspect that this is pypa/pip#6163, but I'm not 100% sure.

[rodcarroll]

It's pypa/pip#6158

Probably worth trying again with 19.0.2 that was released.

After upgrading to 19.0.3 it works. Thank you, this should be closed.
