Package: python3-pip Version: 22.0.2+dfsg-1 Severity: important I found this issue with my local Python project since I just upgraded my testing system to python3 3.10.4-1, which now makes python3.10 the default Python.
I then tested with this simple example repository: https://github.com/pypa/sampleproject Steps to reproduce: 1. Clone the above repository 2. Run `pip3 install --user .` This is the result I observe: Processing /<...>/sampleproject Installing build dependencies ... done Getting requirements to build wheel ... done Preparing metadata (pyproject.toml) ... done Requirement already satisfied: peppercorn in /home/jdg/.local/lib/python3.10/site-packages (from sampleproject==2.0.0) (0.6) Building wheels for collected packages: sampleproject Building wheel for sampleproject (pyproject.toml) ... error error: subprocess-exited-with-error × Building wheel for sampleproject (pyproject.toml) did not run successfully. │ exit code: 1 ╰─> [2011 lines of output] running bdist_wheel running build running build_py running install Traceback (most recent call last): File "/usr/lib/python3/dist-packages/setuptools/_distutils/command/install.py", line 94, in _load_sysconfig_schemes for scheme in sysconfig.get_scheme_names() File "/usr/lib/python3.10/sysconfig.py", line 583, in get_scheme_names return tuple(sorted(_INSTALL_SCHEMES)) RecursionError: maximum recursion depth exceeded while calling a Python object During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/pip/_vendor/pep517/in_process/_in_process.py", line 363, in <module> main() File "/usr/lib/python3/dist-packages/pip/_vendor/pep517/in_process/_in_process.py", line 345, in main json_out['return_val'] = hook(**hook_input['kwargs']) File "/usr/lib/python3/dist-packages/pip/_vendor/pep517/in_process/_in_process.py", line 261, in build_wheel return _build_backend().build_wheel(wheel_directory, config_settings, File "/usr/lib/python3/dist-packages/setuptools/build_meta.py", line 230, in build_wheel return self._build_with_temp_dir(['bdist_wheel'], '.whl', File "/usr/lib/python3/dist-packages/setuptools/build_meta.py", line 215, in _build_with_temp_dir self.run_setup() File "/usr/lib/python3/dist-packages/setuptools/build_meta.py", line 158, in run_setup exec(compile(code, __file__, 'exec'), locals()) File "setup.py", line 20, in <module> setup( File "/usr/lib/python3/dist-packages/setuptools/__init__.py", line 153, in setup return distutils.core.setup(**attrs) File "/usr/lib/python3/dist-packages/setuptools/_distutils/core.py", line 148, in setup return run_commands(dist) File "/usr/lib/python3/dist-packages/setuptools/_distutils/core.py", line 163, in run_commands dist.run_commands() File "/usr/lib/python3/dist-packages/setuptools/_distutils/dist.py", line 967, in run_commands self.run_command(cmd) File "/usr/lib/python3/dist-packages/setuptools/_distutils/dist.py", line 986, in run_command cmd_obj.run() File "/usr/lib/python3/dist-packages/wheel/bdist_wheel.py", line 335, in run self.run_command('install') File "/usr/lib/python3/dist-packages/setuptools/_distutils/cmd.py", line 313, in run_command self.distribution.run_command(command) File "/usr/lib/python3/dist-packages/setuptools/_distutils/dist.py", line 985, in run_command cmd_obj.ensure_finalized() File "/usr/lib/python3/dist-packages/setuptools/_distutils/cmd.py", line 107, in ensure_finalized self.finalize_options() File "/usr/lib/python3/dist-packages/setuptools/command/install.py", line 45, in finalize_options orig.install.finalize_options(self) File "/usr/lib/python3/dist-packages/setuptools/_distutils/command/install.py", line 320, in finalize_options self.finalize_unix() File "/usr/lib/python3.10/_distutils_system_mod.py", line 59, in finalize_unix super().finalize_unix() File "/usr/lib/python3/dist-packages/setuptools/_distutils/command/install.py", line 488, in finalize_unix self.select_scheme("posix_prefix") File "/usr/lib/python3.10/_distutils_system_mod.py", line 55, in select_scheme super().select_scheme(name) File "/usr/lib/python3/dist-packages/setuptools/_distutils/command/install.py", line 522, in select_scheme scheme = _load_schemes()[name] File "/usr/lib/python3.10/_distutils_system_mod.py", line 137, in wrapped_load_schemes _inject_headers(name, scheme) File "/usr/lib/python3.10/_distutils_system_mod.py", line 125, in _inject_headers scheme['headers'] = orig_install._load_schemes()['posix_prefix']['headers'] File "/usr/lib/python3.10/_distutils_system_mod.py", line 137, in wrapped_load_schemes _inject_headers(name, scheme) and then the last four lines repeat hundreds of times until: File "/usr/lib/python3/dist-packages/setuptools/_distutils/command/install.py", line 103, in _load_schemes sysconfig_schemes = _load_sysconfig_schemes() or {} File "/usr/lib/python3/dist-packages/setuptools/_distutils/command/install.py", line 91, in _load_sysconfig_schemes with contextlib.suppress(AttributeError): File "/usr/lib/python3.10/contextlib.py", line 436, in __exit__ return exctype is not None and issubclass(exctype, self._exceptions) RecursionError: maximum recursion depth exceeded in __subclasscheck__ [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for sampleproject Failed to build sampleproject ERROR: Could not build wheels for sampleproject, which is required to install pyproject.toml-based projects I get the same behaviour (obviously) with `python3.10 -m pip install --user .` but `python3.9 -m pip install --user .` works fine: $ python3.9 -m pip install --user .

Deleting the pyproject.toml file allows pip to work with 3.10; this file is minimal: [build-system] # These are the assumed default build requirements from pip: # https://pip.pypa.io/en/stable/reference/pip/#pep-517-and-518-support requires = ["setuptools>=43.0.0", "wheel"] build-backend = "setuptools.build_meta" I've not got further than that, unfortunately.
