Raspberry pi Nupic.core build failed

I have carefully follow the suggested post below.

https://discourse.numenta.org/t/running-nupic-on-raspberry-pi-having-problems/1667

By using pyenv, Nupic core build is failed. Without using pyenv, I could build nupic core on a Raspbery Pi. I can import nupic.bindings in Python.

But, in the last step, when I try to install Nupic from source, I had a following error message.


pi@raspberrypi:~/nupic $ python setup.py develop --user
Traceback (most recent call last):
File “setup.py”, line 134, in
requirements = findRequirements()
File “setup.py”, line 121, in findRequirements
if nupicBindingsPrereleaseInstalled():
File “setup.py”, line 55, in nupicBindingsPrereleaseInstalled
if pkg_resources.parse_version(nupicDistribution.version).is_prerelease:
AttributeError: ‘tuple’ object has no attribute ‘is_prerelease’


I think this error would not be related to Raspbery Pi.

I’ m really wanted to run Nupic on a Rasberry Pi.
Any idea about this error?
