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.
Is there a particular reason you’re trying to set these variables? Are you following a guide that suggests it?
I’m actually not using the default python from the repository, but built and installed a newer python manually. Which causes my python is not in the default directory but under $HOME/.local . In such, I need to set up my own PYTHONPATH .
After I unset PYTHONHOME, I still met some further errors which seem relate to Python:
Traceback (most recent call last):

@zware, I am getting the same error but I don’t have PYTHONHOME or PYTHONPATH set. I am trying to embed python into c++ using pybind11. Here is the simple code:
I installed swift on windows-10. I got similar error when i was trying to run it on command prompt

I got this error

It is an old topic, but just in case still helps someone that figured out yet…
If your context is the same as @ jiapei100 and mine, which is building your “own” python from cpython source code repository (forked). In my case for my C programs to run, I have setup this configuration:
