I updated the version of matplotlib distributed with our group's software to
1.0.0 a week and a half ago (we also use wxPython 2.8.11.0 and Python 2.7).
Since then, multiple users (all on Mac, so far, although we also distribute
a Linux version) have been reporting this error:
RuntimeError : Could not open facefile
/usr/local/bin/phenix-dev-610/build/mac-intel-osx-x86_64/base/Python.framework/Versions/Current/lib/python2.7/site-packages/matplotlib/mpl-data/fonts/ttf/VeraMono.ttf;
Cannot_Open_Resource
The full traceback is appended below. Googling for this turned up multiple
messages relating to older versions of matplotlib, but the only solution I
could find was to remove the fontCache file in ~/.matplotlib (and it appears
that in some cases removing the entire directory is necessary). The problem
is that this appears to be necessary every time a user upgrades to a new
version of our code and removes an older installation, and since we
distribute nightly builds, it has become a daily ritual explaining how to
fix the problem. I would really appreciate it if someone can suggest a more
elegant solution than making my code nuke ~/.matplotlib. Alternately, if
there is a way to completely prevent the creation or use of ~/.matplotlib,
this would make my life much easier; so far this is the only Python module
that I've seen that insists on writing to the home directory and crashes if
it doesn't get its way.
Or do I need to file a bug ticket?
thanks,
Nat
