4.0.2: pytest is failig in test_evm.py with ctypes.ArgumentError

[kloczek]

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix> using 'installer` module
• run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
• build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")

Here is pytest output:

[kabeor]

Hi, v4.0.2 is not maintained any more, plz using v5 branch.

Yeah and other thing is DeprecationWarning about use pkg_resources.

This is a known issue and will be fixed soon, see #2005.

Cannot find what provides those missing pytest fixtures 🤔

Please let me know if you want above patch es as PR.

[XVilka]

@kloczek patch looks good, IMHO. Please send it as a PR to the next branch. Then it can be cherry-picked to the potential 5.0.2 release: #2081

[Rot127]

Should be fixed by #2456 and several previous PRs removing Python bindings and reworking the wheel build (#2400).
