Does it work with python 3.7?

[lsampaioweb]

I have python 3.7 on my Mac OS (High Sierra) and when I try to run "python3 frontend.py" or "python3 backend.py" I get the following error message:

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pyramid/path.py", line 380, in _zope_dottedname_style
found = getattr(found, n)
AttributeError: module 'pyramid_zipkin' has no attribute 'tween'

During handling of the above exception, another exception occurred:

Running "pip3 list" I get:

The problem here is not python 3.7.

There was a backward incompatible change in py-zipkin 0.13. pyramid_zipkin >= 0.21.1 was patched to support it, but you're using 0.21.0.

If you bump all the libraries to the latest version everything should work.

Hi ! Same problem but can't find 0.21.1 version

# pip3 install pyramid-zipkin==0.21.1
Collecting pyramid-zipkin==0.21.1
  Could not find a version that satisfies the requirement pyramid-zipkin==0.21.1 (from versions: 0.4.0, 0.4.1, 0.9.1, 0.11.1, 0.13.0, 0.14.0, 0.15.0, 0.16.1, 0.17.0, 0.18.0, 0.18.1, 0.18.2, 0.19.2, 0.20.0, 0.20.2, 0.20.3, 0.21.0)

Whoops sorry, I just realized we haven't configured travis to upload new versions of pyramid-zipkin to the public pypi.

I've just uploaded the new wheels and this should now work.
