pyproject.toml won't find project name with setuptools python -m build format

What is the correct format for supplying a name to a Python package in a pyproject.toml? Here's the pyproject.toml file:

[project]
name = "foobar"
version = "0.0.1"

[build-system]
requires = ["setuptools>=40.8.0", "wheel"]
build-backend = "setuptools.build_meta"

A build called using python -m build results in the following error.

running check
warning: check: missing required meta-data: name, url
warning: check: missing meta-data: either (author and author_email) or (maintainer and maintainer_email) should be supplied

Based on this reddit post question I had the same issue.

If you are using Ubuntu, then according to this bug report

On Ubuntu 22.04 (Jammy) ensure the environment variable DEB_PYTHON_INSTALL_LAYOUT=deb_system before installing a PEP621 compliant project with pip and setuptools.

That is, do e.g.:

DEB_PYTHON_INSTALL_LAYOUT=deb_system pip install .

instead of:

pip install .

Otherwise, the system may pick up the older version of setuptools (59.x) installed by apt even if you have upgraded setuptools in pip.

Update

At the time the question was asked, setuptools did not have support for writing its configuration in a pyproject.toml file (PEP 621). So it was not possible to answer the question.

Now and since its version 61.0.0, setuptools has support for PEP 621:

Original answer

It seems that you are trying to write a PEP 621-style pyproject.toml with the setuptools build back-end.

But, as of now, setuptools does not have support for PEP 621 yet. The work is ongoing:

Until PEP 621 support arrives in setuptools, one can:
