Install issues OSX Sierra

[bendichter]

Hi,

I am having some installation issues on OSX Sierra. I tried installing binary with conda envs with python = 2.7, 3.5, and 3.6. Each time I get error: Could not find suitable distribution for Requirement.parse('ortools==6.3.4431'). From the issues it looks like only El Capitan binaries are supported. Has this changed? The documentation claims that OSX 10.12 is supported, so I'm confused by this.

Anyway, I proceeded to try to install from source in python 2.7.
make third_party: no error
make python
...
swig -I. -c++ -python -o ortools/gen/ortools/constraint_solver/constraint_solver_python_wrap.cc -module pywrapcp ./ortools/constraint_solver/python/routing.i ortools/constraint_solver/constraint_solver.h:1762: Error: Syntax error in input(3). make: *** [ortools/gen/ortools/constraint_solver/pywrapcp.py] Error 1

I see from the issues that SWIG 3 is required, so I updated SWIG with brew:
brew install SWIG
and I added it to my path in ~/.bashrc:
export PATH="/usr/local/Cellar/swig/3.0.12/bin:$PATH"

swig -version

SWIG Version 3.0.12
Compiled with clang++ [x86_64-apple-darwin16.3.0]
Configured options: +pcre

then make python again. The installation runs without error, but when I try to use the package:

>>> import ortools
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named ortools

ortools-examples does appear to be recognized by pip:

certifi (2017.7.27.1)
ortools-examples (6.3.4431)
pip (9.0.1)
setuptools (36.3.0)
wheel (0.29.0)

I have not been able to get this to work with python 3.5 or 3.6 either. Any suggestions?
