Segfault on first install

[ohadle]

Hi,
I installed juliacall using poetry add juliacall, then opened an existing ipython session, ran the first command and got a segfault. Details:
Shell:

✗ poetry add juliacall

When I reopen Ipython and retry the command I immediately get a segfault.

[cjdoris]

I've only got time to support problems using Tier 1 versions of Julia I'm afraid - whereas ARM Macs only have Tier 2 support right now. This is because the problem is likely to do with Julia itself and not PythonCall.

You could try running things in x86 mode with arch -x86_64 ... (see here: https://medium.com/swlh/run-x86-terminal-apps-like-homebrew-on-your-new-m1-mac-73bdc9b0f343)

Thanks!
