[BUG] pyproject.toml and setup.py missing?

[danihae]

When I install pygmo via pip pip install pygmo, I get this error message, suggesting that a setup.py and pyproject.toml file are missing.

ERROR: pygmo from https://files.pythonhosted.org/packages/e2/12/090ba61479f60d5177a0048736d09dc028b2d65063ed44cb952df506336f/pygmo-v2.19.0.tar.gz does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found.

Thanks for your help!

Hi @danihae

pygmo does not have a fully-fledged and standard-compliant pip-based build system. We have only the bare minimum to produce binary wheels, which are the only supported types of pip packages.

We would need to understand why pip install pygmo attempts to use the source distribution rather than the binary wheels. Specifically:

• are you on Linux? We produce binary wheels only for x86-64 and arm64 Linux platforms, OSX and Windows are not supported;
• if you are on Linux, what kind of distribution are you using? If it is a very old distribution, the binary wheels won't work and pip will attempt an installation from source instead.

Finally, I would suggest you to use conda rather than pip: on conda we have up-to-date packages for all major operating systems and platforms.

Hi @bluescarni

Thanks for the quick response! I use OSX. I now tried conda and it's working well.
