This appears to be an issue with reading the readme as the long description in setup.py. Changing line 466 in setup.py to long_description=open('README.rst', encoding='utf-8').read(), fixes this issue.

Sigh, sorry about that and thanks for the report. You could send a PR if you have the time, or I will get to it soon.

Same issue in line 44

exec(compile(open(fname).read(), fname, 'exec'), info)

exec(compile(open(fname, encoding='utf-8').read(), fname, 'exec'), info) fixed the problem

The install still fails for me on a clean python installation:

        ...
        File "/home/XXX/.pyenv/versions/3.10.6/lib/python3.10/site-packages/numpy/distutils/ccompiler_opt.py", line 717, in _dist_test_spawn
          o = subprocess.check_output(cmd, stderr=subprocess.STDOUT,
        File "/home/XXX/.pyenv/versions/3.10.6/lib/python3.10/subprocess.py", line 420, in check_output
          return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
        File "/home/XXX/.pyenv/versions/3.10.6/lib/python3.10/subprocess.py", line 503, in run
          stdout, stderr = process.communicate(input, timeout=timeout)
        File "/home/XXX/.pyenv/versions/3.10.6/lib/python3.10/subprocess.py", line 1139, in communicate

There seems to be a fix in the arch repos
