Tox with PEP 517 about maturin HOT 8 CLOSED

@davidhewitt Thank you very much for fixing the original bug in tox!

from maturin.

Would it be possible to get an estimate of how long it'll take for this to be fixed? If it's not high on your priority list, is there any way in which I can make a workaround for this?

from maturin.

It's already released

from maturin.

Now I have a new problem...
This is my pyproject.toml:

[build-system]
requires = ["maturin"]
build-backend = "maturin"

This is my tox.ini:

# tox (https://tox.readthedocs.io/) is a tool for running tests
# in multiple virtualenvs. This configuration file will run the
# test suite on all supported python versions. To use it, "pip install tox"
# and then run "tox" from this directory.

[tox]
envlist = py35, py36, py37, pypy3
isolated_build = True

[testenv]
deps =
    pytest>=5.0
    pytest-benchmark
    hypothesis
commands =
    pytest -vvvv

When I try to invoke tox I get:

.package recreate: /home/omer/Documents/Projects/fastuuid/.tox/.package
.package installdeps: maturin
ERROR: invocation failed (exit code 1), logfile: /home/omer/Documents/Projects/fastuuid/.tox/.package/log/.package-2.log

The package can be installed and I'm using it to build the shared library as expected.
Any idea?

from maturin.

@thedrow I forgot to also rename the pyo3_pack directory which I've fixed in 04206b9. With that commit the old error message should return.

from maturin.

Can you release a new version?

from maturin.

FYI as of tox 3.18.1 the issue should be resolved in tox. From local testing when writing maturing examples for pyo3 I think we need #336 to be merged, and then we should be good to update the readme!

from maturin.

I've tested an it works now, however testing locally is tedious due to tox-dev/tox#1634. I'll update the examples
