OSError on Apple M2 Chip

[dchung0741]

Describe the bug
When installing julacall via pip install juliacall and run import juliacall,
I got

OSError: dlopen(/Applications/Julia-1.8.app/Contents/Resources/julia/lib/libjulia.1.8.dylib, 0x000A): tried: '/Applications/Julia-
1.8.app/Contents/Resources/julia/lib/libjulia.1.8.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 
'x86_64')), '/System/Volumes/Preboot/Cryptexes/OS/Applications/Julia-1.8.app/Contents/Resources/julia/lib/libjulia.1.8.dylib' (no 
such file), '/Applications/Julia-1.8.app/Contents/Resources/julia/lib/libjulia.1.8.dylib' (mach-o file, but is an incompatible architecture 
(have 'arm64', need 'x86_64'))

My system

• OS: Mac2023 with M2 chip
• julia version 1.8.5
• If an issue with JuliaCall, the output of pip list or conda list and juliapkg.status():

Package	Version
juliacall	0.9.20
juliapkg	0.1.13
numpy	1.26.4
pip	24.0
scipy	1.13.1
semver	3.0.2
setuptools	69.5.1
typing_extensions	4.12.1
wheel	0.43.0

I could run this a couple of months ago, but failed this week
Thank you!

It seems like you have an x86_64 version of Julia installed in /Applications but a arm64 version of Python. Both need to be the same to work in the same process.

Thanks for the reply.
I think I somehow managed to resolve the issue.
The solution was to install rosetta an the x86 version of Julia.
