AttributeError: 'svmem' object has no attribute 'cached' MacOS, Python 12

[umartini]

Hello,
it seems I need support with running nomination on a Mac.

nominatim import fails:

nominatim import --osm-file oberbayern-latest.osm.pbf

the final verdict from Python is:
AttributeError: 'svmem' object has no attribute 'cached'

crashdump is:

AttributeError: 'svmem' object has no attribute 'cached'

Python is:
(.venv) Rosetta:nominatim-project ullrich$ python --version
Python 3.12.3

nomination is set up in a vent

Should I try another Python version?

It seems the code is for Linux only. I changed it to:
options['osm2pgsql_cache'] = int(min((mem.available) * 0.75,

Yes, we don't have official support for MacOS yet. If somebody feels like setting up a Github CI job for it, then a pull request for that would be warmly welcome.
