Installation Errors

Common errors when installing humanize with pip.

ModuleNotFoundError: No module named 'humanize'

Cause: The package is not installed in the current Python environment.

Fix: Run pip install humanize. If using a virtual environment, ensure it is activated first.

ModuleNotFoundError: No module named 'humanize' (installed but still failing)

Cause: pip installed the package into a different Python than the one running your script.

Fix: Use python -m pip install humanize to install into the interpreter you are running.

ImportError: cannot import name 'X' from 'humanize'

Cause: The function or class does not exist in the installed version.

Fix: Check the version with pip show humanize and upgrade with pip install --upgrade humanize.
