Nope, looks like we're blocked on pyzmq building on Python 3.11.:

Wow, that is annoying:

What even does no-deps mean?

What even does no-deps mean?

You mean --no-deps has no effect on Python 3.11?

[blink1073]

Hmm, let's test that theory...

[blink1073]

Same thing with Python 3.10. Let me try editable mode again.

[blink1073]

Next try is building the sdist first and then installing from that with --pre.

[blink1073]

Okay, this seems like a bug in flit or pip. I don't see why we should be picking up run time dependencies when building a wheel or sdist.

[blink1073]

It isn't a pip bug, because it happens with both pip and build. I think this is related to https://github.com/pypa/flit/issues/354

[blink1073]

Cool, so the solution is not to use dynamic versions with flit, since doing so pulls in the runtime requirements. However, now we're stuck on PyYAML:

         File "/tmp/pip-build-env-93f8_jkm/overlay/lib/python3.11/site-packages/setuptools/_distutils/command/sdist.py", line 312, in _add_defaults_ext
          self.filelist.extend(build_ext.get_source_files())
                               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        File "setup.py", line 204, in get_source_files
          self.cython_sources(ext.sources, ext)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
