[SpotlightKid]

This might be due to insufficiently declared dependencies in the build library used (https://gitlab.com/thiblahute/mesonpep517, or rather my own fork of it).

Can you change your requirements.txt to include meson[ninja] and try again?

[SpotlightKid]

I've updated the rtmidi branch of my fork of mesonpep517, which is used by python-rtmidi, to depend on meson[ninja]. So adding this to your requirements.txt shouldn't be necessary anymore.

Could you test installation from PyPI again?

[briansemrau]

Installation on Windows appears works with no issue. Will later confirm for ubuntu on WSL2.

[SpotlightKid]

Thanks. That sounds promising. Let us know.

[theoparis]

I am having the same issue on NixOS with python3.12 :confused:

[SpotlightKid]

@theoparis Please retry the installation from the source distribution with:

 pip -v install --user --upgrade --no-cache-dir --no-binary python-rtmidi --log python-rtmidi-install.log python-rtmidi

This installs the package under ~/.local/lib and doesn't mess with you system libs.

Please post the contents of python-rtmidi-install.log here (between triple backticks).

You can uninstall it with:

pip uninstall python-rtmidi

To test whether the installation actually works, run

python -c 'import rtmidi; print(rtmidi.__file__); print(rtmidi.MidiOut().get_ports())'

For JACK or pipewire-jack (make sure server is running):

python -c 'import rtmidi; print(rtmidi.MidiOut(rtapi=rtmidi.API_UNIX_JACK).get_ports())'

This should output a Python list of available output port names.

I tried with WSL2 like OP and I get a different error. Strangely it cannot find the mesonpep517 module, while having correctly installed it just before.

Successfully installed cython-0.29.35 meson-1.1.1 mesonpep517-0.2 ninja-1.11.1 packaging-23.1 setuptools-67.8.0 toml-0.10.2 wheel-0.40.0 ... ModuleNotFoundError: No module named 'mesonpep517'

Binary wheel install works perfectly 'tho.

[SpotlightKid]

Looks very much like a WSL2-specific problem to me.

[brunoenten]

There's a chance the migration to python-meson will solve this.

[brunoenten]

confirmed that 1.5.3 installs correctly on WSL2 Ubuntu 20.04 LTS from binary wheel.
