  ERROR: Failed building wheel for lazy-object-proxy
ERROR: Could not build wheels for lazy-object-proxy which use PEP 517 and cannot be installed directly

The versions of the tools are: macos-latest (which apparently is macOS version 10.15; so maybe it is unrelated to #381), The Python version is 3.10.0-alpha.2.

I came here from ionelmc/python-lazy-object-proxy#46.
