This is the problem.
What does config.log say?
hmmā¦ where does pip put config.log?
I am running Xcode 9 though, so I wonder if the developer tools are too new(?)
Looks like my system only has LLVM + Clangā¦ no gcc. Installing now
Okay, I installed gcc (via conda), but same error(s). Is it because Iām using conda?
I was able to replicate your problem, and here is my workaround.
Try downloading capnproto-c+Ā±0.6.0 tarball separately.
cd capnproto-c++-0.6.0/
./configure
make
sudo make install
CFLAGS="-mmacosx-version-min=10.7 -std=c++11 -stdlib=libc++" pip install pycapnp --user
That seems to work for me.
I have to step away for a bit, but will try a little later.
Thanks for your help. Much appreciated.
Well, this fails during āmakeā:

Iām going to be building a Linux box for keras/tensorflow later, so maybe Iāll try again under Ubuntuā¦
This sounds like progress. Now you can point to the C++ build as the culprit instead of some nebulous python/pip issue.
Wowā¦ okay, up and running on my keras/tensorflow Ubuntu box in about 20 mins!
Do you know if any specific routine is required (or available) to take advantage of cuda?

Iām having the exact came problems. Same setup as jacobeverist. I tried his approach using:
CFLAGS="-mmacosx-version-min=10.7 -std=c++11 -stdlib=libc++" pip install pycapnp
It gives a RuntimeError: Configure failed.
It still seems to be using ā/Python.framework/Versions/2.7/lib/python2.7/ā when it installs. If Iām understanding correctly I want it to be using the Mac installed python, not the Python 2.7 I installed from python.org, which it seems to be using. Itās weird because when I run āwhich pythonā command it is running ā/usr/bin/pythonā
Is there some way to force the install to use the Mac system python?
Thanks to @jacobeverist for this solution. I spent a full SEVEN HOURS trying to get Nupic installed on a Mac OS X 10.13 (High Sierra).
I had slight variations in the procedure, including pycapnp version 0.6.3, and pip install pycapnp without the compiler options. Also, my previous configuration was Anaconda Python 3.6, so it took many steps for me to install and configure Python 2.7 and virtualenv to create an environment with 2.7 and packages just for Nupic. Then I installed all the requirements.txt EXCEPT nupic.bindings. Finally I followed steps 1 thru 4, in this post.
To @rhyolight ā it would be really great if the Nupic Readme.md page could be updated with better instructions for Mac installation, reflecting these steps.
Where in the README do you think is the best place to put a note or something that links to this solution? Or maybe even better, what are the keywords that would would have brought you to this thread sooner?
I realise this is a reply to an old post but I just went through the process of installing nupic on my Mac (High Sierra) and here is worked for me. I use conda for environment management so thatās where I began. I was able install nupic and get the unit tests running without setting any additional flags.
# create a new environment and activate
conda create -n nupic python=2.7
conda activate nupic
# install 0.6.3 of pycapnp
conda install -c conda-forge pycapnp=0.6.3
# install nupic.core and nupic
pip install nupic.bindings
pip install nupic
# run tests
cd $HOME/code
git clone https://github.com/numenta/nupic.git
cd nupic
py.test tests/unit
