Can't install pyo using pip

Question

When trying to install pyo using pip I get error

$ pip install pyo

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

Then I tried

$ pip install pyo --use-deprecated=backtrack-on-build-failures

DEPRECATION: Backtracking on build failures can mask issues related to how a package generates metadata or builds a wheel. This flag will be removed in pip 22.2. A possible replacement is avoiding known-bad versions by explicitly telling pip to ignore them (either directly as requirements, or via a constraints file).

The python version

$ python --version

Python 3.10.4

Tried to install AJAX SOUND STUDIO pyo

For AJax Sound studio I tried with latest pyo 0.9.1 but still error persists so I tried with pyo 0.8.4.

Still the issue is not solved.

The above terminal output is from Anaconda Promt from Windows. I also tried to install pyo in Ubuntu. In that OS also I am facing issues with installing PYO.

Terminal output for installation in Ubuntu

$ pip install pyo

Terminal output

tried to install pyo using conda but package is not found

$ conda install pyo

@MadPhysicist I had an issue with installing pyo using pip. Got solved by downgrading python version to 3.9 as CristiFati mentioned. So waiting for CristiFati answer so that I can mark that as answer. — VA splash, Aug 27 '22 at 17:40
Could you please test the *.whl* that I built for *Python 3.10*. I want to see if it behaves well in your environment / scenario (and it doesn't contain bugs that I didn't detect in my (shallow) test)? — CristiFati, Sep 06 '22 at 10:59

Looking at [PyPI]: pyo 1.0.4 - Download files (newest published version at answer time), prebuilt .whls (for Win) are available if all below apply:

Python version: v3.9, v3.8, v3.7, v3.6
Python arch: pc064 (win_amd64)

Also, building from sources (fall back if no prebuilt .whl available), is complex (and doesn't work OOTB - only tried for Win, but I'm 99% sure that it's the same for Nix) as it requires some additional steps (building / using a bunch of dependencies), so the error pops up (if fixed, another will, and so on).

So, stick with supported Python versions until a new PyO version will be released (this one is 1+ year old).
Of course building from sources is an option, but it requires deeper knowledge.

Update #0

Built .whls and published them on [GitHub]: CristiFati/Prebuilt-Binaries - (master) Prebuilt-Binaries/PyO/v1.0.4 (win_amd64 for Python: v3.11, v3.10 and win32 for current Python versions). Check [SO]: Installing pygraphviz on Windows 10 64-bit, Python 3.6 (@CristiFati's answer) (Shortcut section at the end) for details regarding custom .whl installation.

I used the following script to (quickly) test them.

code00.py:

#!/usr/bin/env python

import sys
import time

import pyo


def main(*argv):
    sample_name = "Sine"
    sample_class = getattr(pyo, sample_name, None)
    if sample_class is None:
        print("Invalid sample: {:s}".format(sample_name))
        return -1
    secs = 2
    out_file = "{:s}.wav".format(sample_name)
    srv = pyo.Server().boot()
    print("Playing sound ({:s}) for {:.3f} seconds (and saving to '{:s}') ...".format(sample_name, secs, out_file))
    srv.start()
    srv.recstart(out_file)
    sample = sample_class(mul=0.01).out()
    print("Sample: {:}".format(sample))
    time.sleep(secs)
    srv.recstop()
    srv.stop()
    sfp = pyo.SfPlayer(out_file)
    print("SFP: {:}".format(sfp))


if __name__ == "__main__":
    print("Python {:s} {:03d}bit on {:s}\n".format(" ".join(elem.strip() for elem in sys.version.split("\n")),
                                                   64 if sys.maxsize > 0x100000000 else 32, sys.platform))
    rc = main(*sys.argv[1:])
    print("\nDone.\n")
    sys.exit(rc)

Output:
