What is the problem? Our requirements file is here:
https://github.com/urievenchen/speedy-net/blob/master/requirements.txt

It doesn't fail with Python 3.5.2

Pillow 3.4.2 provides binary wheel for Python 3.5, but not for 3.6.

So your pip can just install wheel on Python 3.5, but it is required to build
on Python 3.6. And your machine doesn't have zlib which is required
to build Pillow.

Easiest solution may just update your requirements to Pillow==4.0.0.
Pillow 4.0.0 provides binary wheel for Python 3.6, from 2017-01-02.
https://pypi.python.org/pypi/Pillow/4.0.0

Thank you, I'll consider to update our requirements to latest versions of
all packages. Last time I checked in 22th December 2016 and all our
requirements were the latest versions. In the meantime we can keep using
Python 3.5. By the way, Travis CI tests passed with the same requirements
and Python 3.6 (and 3.5 and 3.4). How did it install the requirements
there? Does it depend on the operating system?

I see now that Python 3.6.0 was released on 2016-12-23.

By the way we use Ubuntu 16.04 in production with Python 3.5.2, so it's not
that important to support Python 3.6 right now. What are the reasons to
upgrade Python to 3.6?

Thanks,
Uri.

Go here http://www.lfd.uci.edu/~gohlke/pythonlibs/#pillow to get what you need.

In all my years of downloading from this site I've never, ever had a problem.

Kindest regards.

The same as for any new version:
New features -- see What's New in 3.6.
New bug fixes.
New performance improvements.

Reasons against:
The effort to make sure all dependencies are available for 3.6*
Possible regressions.

* For Windows, any of the 381 wheels available from
http://www.lfd.uci.edu/~gohlke/pythonlibs/
should be available in 3.6 versions (unless there was a major problem in
recompiling).
