I see your PYTHONHOME is set to PYTHONHOME = '/home/env3/educ'. Try to check if it is really there.
The solution for me was to remove the PYTHONHOME environment variable.
For you, it can be just that, or setting that variable to another value.
This worked on Windows, and would work on Linux for sure. If someone tries this on Linux, please post a comment here !
A CPython developer confirmed the solution here. :
This is not a Python bug, this is a symptom of setting PYTHONHOME and/or PYTHONPATH when they’re not needed. In nearly all cases you don’t need to set either of them;
In the case of PYTHONHOME it’s almost always a mistake to set.
