pip install nupic gives error "Command "python setup.py egg_info" failed with error code 1 in..."

[cpoptic]

I'm running Windows 10.
To reproduce the error:

I've created a virtual environment "numenta-env" with python=3.6
activate numenta-env
pip install nupic

It begins installing and then halts while collected unittest2==0.5.1 (from nupic)

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Chris\AppData\Local\Temp\pip-build-r5de8_q3\unittest2\

Here is the complete output after running pip install nupic

I've tried unintstalling and reinstalling setuptools, but no joy.
Incredibly frustrating to sink several hours debugging and reinstalling packages with zero to show for the effort.

Same here. I'm using python 3.5 fresh install and here is the error msgs

It seems like Nupic only works for Python 2.7 so this issue should be closed.
According to my knowledge Python 2.7 will not be maintained past 2020 though.

[MZamanMughal]

No same here for python 2.7 @MikeZhu92

[MikeZhu92]

Is that for Ubuntu or Windows ?
Ubuntu works for me at least.
For windows platform I would recommend to check the C++ compiler.

@MZamanMughal Are you saying that you go this error with python 2.7? This error looks like a python 3 error. Sometimes it happens when you have multiple pythons installed and the wrong one is being invoked.

@MikeZhu92 Happened for Mac too...

To Everyone having this problem: Try uninstalling NuPIC completely, then run pip install nupic [--user] again. Make sure you are not running python 3.

[ibobak]

Guys, now is the year 2019. Python 2 will soon be shut down. We all are migrating code on Python 3.

And, until now you did not do migration onto Python 3 ???

[rhyolight]

This codebase is in maintenance mode. New HTM python code will not be written here. See the community fork for Python 3.

[arb-git]

Thanks @rhyolight!
Though the community fork also has a problem, which makes it unusable:

ERROR: Could not find a version that satisfies the requirement nupic.bindings>=1.0.6 (from nupic==1.0.6.dev0) (from versions: 1.0.1)
ERROR: No matching distribution found for nupic.bindings>=1.0.6 (from nupic==1.0.6.dev0)
