Re: [Matplotlib-users] Crash on import with CGI wrapped by PHP--unhappy with .matplotlib directory?

[\Jonathan H. http://JonathansCorner.com\ <jon...@po...>]

Tried that and reran it; I'm getting substantially the same stacktrace:

  File "/home/jhayward/bintmp/test.py", line 5, in <module>
    import matplotlib;
  File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
639, in <module>
    rcParams = rc_params()
  File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
562, in rc_params
    fname = matplotlib_fname()
  File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
513, in matplotlib_fname
    fname = os.path.join(get_configdir(), 'matplotlibrc')
  File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
207, in wrapper
    ret = func(*args, **kwargs)
  File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
403, in _get_configdir
    raise RuntimeError("Failed to create %s/.matplotlib; consider setting
MPLCONFIGDIR to a writable directory for matplotlib configuration data"%h)
RuntimeError: Failed to create /root/.matplotlib; consider setting
MPLCONFIGDIR to a writable directory for matplotlib configuration data

It's /path/matplotlibrc and not /path/.matplotlibrc or anything like that?
