When I run localserver on googleappengine error is "File "~/dev_appserver.py", line 102, in <module> assert sys.version_info[0] == 2 AssertionError"

Question

I think that this problem is due to the python version. I used Anaconda with python 3.6 for learning django. Now I've to work on google app engine using python2.7. I uninstalled anaconda. Now when i run "python" I get: "Python 3.6.1 |Continuum Analytics, Inc.| (default, May 11 2017, 13:09:58)". Is there a way to default back to python2.7?

I'm on ubuntu 16.04

edit: problem is not due to python version

Answer 1

Since you are using Anaconda, you can create a new virtual environment by typing:

conda install -n yourenvname [package]

So with python2.7 installed:

conda create -n python2 python=2.7 anaconda
source activate python2

And if you want to leave the virtual environment:

source deactivate python2

If you want to list all of your virtual environment:

conda env list

This way, it will not interfere with your existing python 3.6. Be aware of these command are used for conda, another command pip is for another case.
