Doesn't sound like you have Python installed. You also don't mention which branch you are working from -- anything other than the py3 branch is very unlikely to work.

[gregneagle]

If you are using the py3 branch, then you'll need to install Xcode. python3 in the virtual environment's bin directory points at Xcode's python:

python (latest: 3.12.5) and xcode (downloaded from the appstore) are installed.
same error.

[gregneagle]

If you look at the symlinks in the virtual env, they are looking for Python 3.9.x.

The Python included with Xcode 15.4 is Python 3.9.6.

$ /Applications/Xcode.app/Contents/Developer/usr/bin/python3 -V
Python 3.9.6

[gregneagle]

And again: it sounds like maybe you are trying to use the Python2 demo zip file, which is unlikely to work at all.

[ziltsh]

I think the mwa2_demo.zip from the py3 branch may be the same as the one from the main branch - as in the URI's mentioned in the README.md are the same.
How can one download the mwa2_demo.zip for and with Python3 ?

[gregneagle]

I don't think anyone has created a mwa2_demo.zip for Python 3. The major obstacle there is that Apple does not include Python 3. A zipped up virtual env has to at least know where the python interpreter is. If Python 3 is installed by the nature of having Xcode, it's in one place. If instead, you installed the command-line dev tools, it's in a different place. If you installed via the Python.org package, it's in a third place. If you installed via Homebrew or Anaconda or MacAdmins Python or...
