AttributeError: 'function' object has no attribute 'cache_clear'Additional notes
Caused by pypa/pip#13306 - you may want to catch AttributeError when running finder.find_all_candidates.cache_clear(), then attempt to run finder._all_candidates.clear()
Workaround
Use pip v25.0 or lower
pip install 'pip < 25.1'Metadata
