python-pillow cannot open font resource #23

Closed frasertweedale closed 8 years ago

frasertweedale commented 8 years ago

Visiting /user results in a 500 Internal Server Error. It seems Pillow cannot open a font file.

I guess something is missing from the deploy guide, or some initialisation is not being performed by the program.

This occurs with Pillow 2.8.2 from Fedora repos as well as 2.9 from PyPI.

OK so it was weird perms for package data (android .ttf) in captcha library.

Uninstall and reinstall fixed it for me:

sudo pip uninstall captcha
sudo pip install captcha
