backboneelement ImportError - Python 3.4.2

[p2]

I've just tested latest master and it works fine with Python 2.7.10 and 3.5.1. Which branch/version are you on?

[dostergaard]

I just cloned the master as follows:
git clone https://github.com/smart-on-fhir/client-py.git
cd client-py
virtualenv -p python3 fcenv3
. fcenv3/bin/activate
pip install -r requirements_flask_app.txt
python flask_app.py

I just tried it again but this time on my Gentoo box running python v3.4.3 with the same results.

Oh, and I agree it works fine using python 2.7.10.

Huh, this is weird. It's a circular import which doesn't happen in 2.7 and doesn't happen in 3.5, but on 3.4? Not sure why that is.

I had the same issue on Cygwin after following the build instructions in the README.md, Python 3.4.5.

For me, the following has flask_app.py up and running:
