Permission denied when importing matplotlib.pyplot using python

Question

I get this trackback when importing matplotlib .

import matplotlib.pyplot as plt
/Users/ny/anaconda/lib/python3.5/site-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
  warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')

    font = ft2font.FT2Font(fpath)

PermissionError: [Errno 13] Permission denied: '/Library/Fonts/WarnockPro-Subh.otf'

How do I fix it?

Answer 1

It looks like the user executing the process does not have access to the file /Library/Fonts/WarnockPro-Subh.otf or one of it's parent directories.

Have you tried to chown the file or directory?

chown user_name file
chown user_name folder
chown -R user_name folder #recursive
