Abjad 3.18 does not support Python 3.13?

While trying to install Abjab as per your instructions, I got the following error code:

× Getting requirements to build wheel did not run successfully.
│ exit code: 1
╰─> [3 lines of output]
This is Abjad 3.18, which supports Python 3.10, 3.11.

  But it looks like you're trying to install Abjad with Python 3.13.
  [end of output]

Is this something that needs to be fixed or did I make some sort of error? Thanks!

No, it’s not something I have control of though. The abjad people haven’t made it compatible with python >3.10. So to use abjad, you’d need to use an older version of python.

You can always use musicxml output still, though.
