@oscar6echo upgrade your version of setuptools, there was a backwards incompatible release jupyter/jupyter-packaging#130

[oscar6echo]

@timkpaine Thx for the swift reply.

Yes, I have traced down the problem to these lines in jupyter_packaging/setupbase.py:

try:
    from setuptools.config import StaticModule
except ImportError:
    # setuptools>=61.0.0
    from setuptools.config.expand import StaticModule

In my conda env the packages are all updated:

❯ conda list jupyter-packaging
# packages in environment at /home/olivier/miniconda3/envs/jlab-ext-examples:
#
# Name                    Version                   Build  Channel
jupyter-packaging         0.12.0             pyhd8ed1ab_0    conda-forge
❯ conda list pip
# packages in environment at /home/olivier/miniconda3/envs/jlab-ext-examples:
#
# Name                    Version                   Build  Channel
pip                       22.1               pyhd8ed1ab_0    conda-forge
❯ conda list setuptools
# packages in environment at /home/olivier/miniconda3/envs/jlab-ext-examples:
#
# Name                    Version                   Build  Channel
setuptools                62.2.0          py310hff52083_0    conda-forge

But where I run pip install --no-clean -e . it still breaks as I mentionned above.
The reason is that in the /tmp/pip-build-env-XXX I see in /overlay/lib/python3.10/jupyter_packaging/setupbase.py I see:

from setuptools.config import StaticModule
[...]
__version__ = '0.10.6'

For some unknown (and annoying) reason pip uses an outdated version in the build process while all is up to date in my working env. I imagine there must be some config somewhere to correct that ?

Even more intringuing: Where I pip install -e . the hello world example from https://github.com/jupyterlab/extension-examples I see no such error, though I am in the SAME env.....

Thanks for reporting @oscar6echo, you can look at #31 to correct your extension to fix the issue.

@fcollonval thx for the swift fix. It works now overhere.

I realize now that I failed to notice the difference between hello-world//pyproject.toml and mimerender-cookiecutter-ts//pyproject.toml. This minor version has a big impact !
