flake8-copyright

0.2.4 verified Fri May 01 auth: no python

A flake8 plugin that checks Python files for copyright notices in their header comments. Version 0.2.4; stable but low activity.

pip install flake8-copyright

Common errors

error ModuleNotFoundError: No module named 'flake8_copyright' ↓

cause The plugin is not installed or the import path is wrong.

fix

Run: pip install flake8-copyright

error flake8: error: unrecognized arguments: --copyright-check ↓

cause The plugin is not loaded; flake8 doesn't know about the options.

fix

Ensure flake8-copyright is installed (pip list | grep flake8-copyright) and run flake8 again.

gotcha The plugin requires flake8 to be installed separately. ↓

fix Install flake8: pip install flake8

gotcha Copyright regex uses Python re.match; it must match from the beginning of file. ↓

fix Use a regex that starts matching from the first line, e.g., Copyright \d{4} MyCompany

gotcha The 'copyright-min-file-size' default is 10 bytes; files smaller than this are skipped. ↓

fix Set copyright-min-file-size = 0 to check all files.
