Bug report
This bug was opened in response to a comment on Bug #12176
When importing pyplot on macOS High Sierra with Python 3.6.5 and matplotlib 3.0.0, fontlist-v300.json cannot be found and at the conclusion of the resulting search, permission is denied via Permission denied: '/opt/local/share/fonts'.
Code for reproduction
