Fails to install

[ekkis]

I'm following the install instructions on MacOS Sonoma 14.6.1 using:

% pipx install docsend

to which I get:

Fatal error from pip prevented installation. Full pip output in file:
/Users/ekkis/.local/pipx/logs/cmd_2025-01-10_16.25.00_pip_errors.log

pip seemed to fail to build package:
pillow<6.0,>=5.3

Some possibly relevant errors from pip install:
error: subprocess-exited-with-error
KeyError: 'version'

Error installing docsend.

here are the contents of the logfile:
