Questions
The path /App****/Python3.framework/Versions/3.9/lib actually doesn't exist in my PC, so I think maybe it's because somewhere point to a wrong $PATH.
I found where the true python lib path is, and added it to $PATH, since this error seems due to lib not in the path:
sudo find /Library -name "python*"
# so here I got the python3 lib path in my PC
export PATH=/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib:$PATH
# re-run
gopy build -output=out -vm=python3 github.com/go-python/gopy/_examples/hi
# still the error output

I got around this by passing the absolute path for the python binary to the -vm flag

But the error I'm seeing is

Can you try setting the env variable -
ARCHFLAGS=-arch arm64?Also try
GOARCH=arm64andGOOS=darwinb-long commentedon Apr 2, 2025
Hi all 👋
Something that may help, is a cookiecutter for gopy. I've created one (it isn't perfect, but it is essentially the same code that I'm using for two projects).
Here's the cookiecutter I built:
macOS and M1 (ARM64)
Currently, this cookiecutter is cross-platform for macOS and Linux. The build, test, and publishing all works and you can see real examples in the projects below.
The builds for ARM64 work just fine 👍 🙂
Projects based on this structure
My two projects (published to pypi.org) based on the above project structure are here:
They are only pushing python 3.11 and 3.12 wheels, but since I'm using Github's matrix style builds, it only takes a line or two change to experiment.
Please feel free to open PRs or experiment with any of the above and please share any experimenting that you do publicly!
