Creating Nikola Site
====================

This is Nikola v7.8.14.  We will now ask you a few easy questions about your new site.
If you do not want to answer and want to go with the defaults instead, simply restart with the `-q` parameter.

This is not a problem with Nikola. This happens because you’re on an outdated version of macOS, and attempting to use packages compiled for 10.12.

If you installed Pillow using the wheels provided by the Pillow project (pip install does that by default): report a bug to them. You should be able to reproduce with python -c "from PIL import Image" instead of calling Nikola. Those packages claim 10.6+ compatibility, but apparently have some problems? — Try reinstalling Pillow first.

Thank you

@Kwpolska I hope you'll forgive me for posting here a link to the relevant open issue on the Pillow tracker in case anyone else stumbles across this thread in future: python-pillow/Pillow#3068

Posting a link is completely fine, as was your original query — while this is not a Nikola bug, it was encountered while running it and could have been an issue on our part as well.
