Thread: [Matplotlib-users] font path problem

Hi
I have just installed matplotlib and Python 2.3.3 for Windows (Enthought 
Edition) on Win XP. Then I ran the sample at:
http://matplotlib.sourceforge.net/screenshots/simple_plot.py. It caused 
the traceback below, related to the ttfcache
I have tried:
1. Created a System Environment variable called ttfcache that points to 
C:\Documents and Settings\gventer\Local Settings\Application Data
(which is where the Windows font cache file IconCache.db is)
2. Created a folder in %USERPROFILE%\\.ttffont.cache - (that is 
C:\Documents and Settings\gventer\.ttffont.cache)
Every time I still get:
Traceback (most recent call last):
 File "C:\myscripts\simple_plot.py", line 1, in ?
 from matplotlib.matlab import *
 File "C:\PYTHON23\Lib\site-packages\matplotlib\matlab.py", line 133, in ?

 from font_manager import FontProperties
 File "C:\PYTHON23\Lib\site-packages\matplotlib\font_manager.py", line 
944, in ?
 fontManager = FontManager()
 File "C:\PYTHON23\Lib\site-packages\matplotlib\font_manager.py", line 
790, in __init__
 pickle.dump(self.ttfdict, file(ttfcache, 'w'))
IOError: [Errno 2] No such file or directory: 
'%USERPROFILE%\\.ttffont.cache'
What else could I try?
Thanks
Gerhard

To answer my own question - I commented out line 790 in font_manager.py:
#pickle.dump(self.ttfdict, file(ttfcache, 'w'))
This fixed it for me
