Install failed

I'm relatively new to python, and I got chip working, but after reboot its not working anymore:

chip@chip ~/dev> sudo python3 test.py 
[sudo] password for chip: 
Error processing line 1 of /usr/local/lib/python3.4/dist-packages/easy-install.pth:

Traceback (most recent call last):

    import CHIP_IO.GPIO as GPIO

I'm wondering why chip_io isn't available by a package manager?

Rerunning setup fails as well:

Any ideas?

Gotta standby a bit, so much food in my belly from Thanksgiving and the stout I've had to drink isn't helping anything.

The test.py script has to be run from within the CHIP_IO directory and there will most likely be issues with some of the tests.

You do need the DTC compiler, that NTC provides, installed before installing CHIP_IO.

I don't personally use Python3, so there most definitely could be an install issue. I'll have to get my dev CHIP up and running when I get home to test it out.

As for the the package manager, it can be installed via pip since I uploaded a version there (can't remember which one though).
It was mentioned by @computermouth that it could possibly be added to the CHIP repo, so that could happen in the future.

Ok, back home and looked over stuff. I just installed CHIP_IO under Python 2.7.9 and Python 3.4 on a freshly flashed headless CHIP. No errors in either install.

I rebooted the CHIP and tried the Python3 install again. No issues.

What does your test.py script look like?

So i got it working with python2.7. I reran the whole install instructions again, and it installed the dtc dependencies again... prob. that might have been missing. Anyways its working now. Thanks for checking!

Glad it worked out!
