python version error

[palfeng]

Hello, I'm a new user for Nifty4Gemini to reduce NIFS data. After I installed geminiconda following https://www.gemini.edu/observing/phase-iii/reducing-data/gemini-iraf-data-reduction-software and I download the Nifty4Gemini codes in this github, I still cannot install Nifty4Gemini since it warns that the python version is wrong (while I do have the correct version). I attach the screenshot below. Can you please advise where is wrong? Thanks!

Ok. The above issue is solved once I downgrade my python to 2.7. But I still cannot load "import nifty" and the error is:

import nifty
Traceback (most recent call last):
File "", line 1, in
File "/home/parallels/anaconda3/envs/geminiconda27/lib/python2.7/site-packages/pyraf/irafimport.py", line 116, in _irafImport

ImportError: No module named getConfig

I have changed that there is indeed a file call GetConfig.py in the correct path, but not sure why it is error. Can you please help? Thanks!
