CANCELED: Problem installing janus_swi for SWI 10.0.2

Installing
1

On MacOS 15.7.4 with SWI 10.0.2 from brew.

I am building a python virtual environment based on poetry (I am not sure this is relevant).

The project file pulls JANUS SWI from git:
"janus-swi @ git+https://github.com/SWI-Prolog/packages-swipy.git"

But when I try to run my system, I am getting this error:

  File "/Users/rpg/Library/Caches/pypoetry/virtualenvs/legend-L1facsQ6-py3.12/lib/python3.12/site-packages/janus_swi/janus.py", line 63, in <module>
    import janus_swi._swipl as _swipl

I am not sure how _swipl.cpython-312-darwin.so is built, downloaded, or otherwise installed, so I don’t know how to get it to reference the proper libswipl version.

This problem turned out not to be a SWI prolog problem. It was actually the poetry virtual environment manager being too aggressive in its caching. Smashing the poetry/artifacts and poetry/caches directories fixed the problem

Sorry about the noise.
