I've tried everything, even downgrading Poetry and blurhash-python but it keeps failing whereas it works on my local development device (macbook air M1 14.3).

The only issue I found similar to this error is: Installing a package that depends on setuptools fails intermittently: Backend 'setuptools.build_meta:legacy' is not available. #7611 on Poetry repository but no luck.

Maybe pyproject.toml file needs updating its build backend.

Hi,

The log you pasted above contains a clue what the issue could be:

#13 94.79   gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -Isrc/ -I/tmp/tmp1a5eylby/.venv/include -I/var/lang/include/python3.10 -c build/temp.linux-aarch64-cpython-310/blurhash._functions.c -o build/temp.linux-aarch64-cpython-310/build/temp.linux-aarch64-cpython-310/blurhash._functions.o -std=gnu99
#13 94.79   error: command 'gcc' failed: No such file or directory

That looks a lot like gcc, which is required to build the package from source, is not installed on the runner by default.

I tried installing blurhash on my computer using Poetry 1.7.1, from both wheel and source distribution. Both methods were successful, so the issue shouldn't be with the package.

I figured out a way to build wheels for aarch64. I'm releasing a new version, 1.2.2, which adds wheels for Python 3.12 and aarch64 architecture, for every supported Python version. I'm using qemu to build and test the wheels, so hopefully it'll work on real hardware too 🤞

I have released the new version: https://pypi.org/project/blurhash-python/1.2.2/. You should be able to install it without gcc. Let me know if you're unable to install the new version.
