How To Reproduce

Tell us how to reproduce the issue.

python3.11 -m venv venvs/scancode-32.0.0-py311/
source venvs/scancode-32.0.0-py311/bin/activate
pip install scancode-toolkit
scancode -h

System configuration

For bug reports, it really helps us to know:

• What OS are you running on? (Windows/MacOS/Linux) ubuntu-20.04
• What version of scancode-toolkit was used to generate the scan file? v32.0.0
• What installation method was used to install/run scancode? (pip/source download/other) pip

@jyang pointed out that the setup.cfg at https://files.pythonhosted.org/packages/88/4b/79ca4c6f06c5b9ad1f5f601f1191e207fa05dcbccb2c4a46b381d3ad98af/scancode-toolkit-32.0.0.tar.gz is different from the one we have in https://github.com/nexB/scancode-toolkit/blob/develop/setup.cfg#L198
in terms of where the summarycode.classify_plugin:FileClassifier is located in entry_points. It is in pre_scan in the former, and in post_scan in the later, which is causing the failure.

So the issue was that we had a setup-mini.cfg which was not consistent with setup.cfg and some updates were only applied to the later. As we use the setup-mini.cfg to build the python sdists and wheels, this was creating the issue in pip install, but not in the release archives. Fixed in the PR above ^
