I am having a lot of trouble installing the previous version of swi-prolog. For some reason, updating to 9.0.0 does not work with my codebase which uses pyswip. Could someone kindly help? =)

@Jacktopping56 When installing pyswip use this command in your venv: pip install git+https://github.com/yuce/pyswip@master#egg=pyswip This will install the latest version of pyswip that fixed the issue on Mac.

Note that the homebrew package information is just a git repo. That means you can do anything git – in particular, reset back to a state in history. After that, when you uninstall the problematic package and then reinstall it, you’ll get the version that was latest at that point. And in particular,…

It finally works! The thread suggested by @EricGT was very useful. Here is how: For some reason downloading SWI-Prolog 8.4.3 from the website is causing me another slew of errors.

Does anyone know if this works with Mac, I am trying to use Swi Prolog with Python for a project at university. I believe it doesn’t work with the current version 9. So I want to downgrade so I can use it

@Jacktopping56 How did you install swi-prolog?

I’m not a Python user, but the stack locations hint that it is using some bundled version of pyswip?

I installed it via Homebrew, I then seem to get the error that it is not compatible with arm64 and that it needs x86_64

Have you tried opening swi-prolog in your terminal using the swipl command? This should determine whether it is swi-prolog or your python code. Homebrew should install it with no problems.

Yes, when I use the swipl command via terminal it works. Someone has the same issue via Error when importing PySwip · Issue #76 · yuce/pyswip · GitHub , someone seems to have fixed this but I’m struggling to interpret what it is saying
