PIP failed building wheel for rtmidi-python (subprocess-exited-with-error and legacy-install-failure)

PIP failed building wheel for rtmidi-python (subprocess-exited-with-error and legacy-install-failure)

Hello everyone, I'm facing an issue with pip while installing rtmidi-python on my Raspberry Pi 4B running Raspbian 11.

The building wheel keeps failing for that package only and I get two errors: subprocess-exited-with-error and legacy-install-failure.

Here's the output for the command pip install rtmidi-python :

pi@raspberrypi:~ $ pip install rtmidi-python

× Encountered error while trying to install package.
╰─> rtmidi-python

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

Pip (22.0.4) and Python (3.9.2) are up to date.

I tried to manually download the package from PyPI (https://pypi.org/project/rtmidi-python/#files) to install it with python setup.py install but it does not seem to install anything : Here's the output:

pi@raspberrypi:~/Downloads/rtmidi-python-0.2.2 $ sudo python setup.py install

Writing /usr/local/lib/python2.7/dist-packages/rtmidi_python-0.2.2.egg-info

For some, that might be a problem with setup.py but I don't know much more. I've been looking for solutions on tons of forums without success. Your help would be appreciated.

Thank you all.

Solution

  • The tp_print method was removed from the API in Python 3.8. Error "'PyTypeObject' {aka 'struct _typeobject'} has no member named 'tp_print'" means that the code is intended for Python <= 3.8. Downgrade to Python 3.8 and try again.

    Let's look at rtmidi-python: https://pypi.org/project/rtmidi-python/#history . Currently the only released version is 0.2.2. The version was released at Feb 5, 2014. It looks too old, I'm not sure it could work with Python 3 at all. Try Python 3.8 and then Python 2.7.
