Error installing meson-python with brew (MacOSX 10.15.7)

[rogeriod]

I have Python 3.12.2 and Meson 1.3.2 installed. When I attempt to install meson-python with brew, I get this error message ... any ideas as to how to resolve this? I'm on a Mac Intel running MacOSX 10.15.7 (Catalina). Thanks!

It looks like an Homebrew issue. meson-python works just fine with Homebrew.

You can install meson-python for the Homebrew Python installation with pip: python -m pip install meson-python.

When installed from the cmd line as you've suggested, it's still not visible to brew ...

Yes, if you install a Python package via pip, the Homebrew package manager will not know about it. If you need the Homebrew package installed as a dependency for compiling some other package, you need to fix the meson-python Homebrew package. However, you are running an unsupported version of Homebrew...

You'll have to ask the homebrew developers what the error message means since it's a homebrew error message, not a meson-python error message.

Thank you both @dnicolodi and @eli-schwartz. I'll look into issue on the homebrew side. Thanks again!
