Hi All,
I installed the matplotlib0.91.2 on 64-bit Ubuntu7.04 system. I ran an
example code and got the error:

MPLCONFIGDIR to any writable directory where you want matplotlib data stored
"%h)
TypeError: not enough arguments for format string
How can I get it fixed?
Thanks,
Brook

We might be in a better position to help if you post the example code.

This bug was first pointed out by Mark Hamilton (with a patch) in the
thread "RuntimeError in _get_configdir". I've committed his fix to
svn. Basically, the format string is looking for two arguments where
only one is provided. Because it only arises in an error condition,
it is a corner of the code that had not been hit before.

Hi Brook,

This is the crucial bit.
Looks like you've set MPLCONFIGDIR to a read-only dir, or the .matplotlib in the current dir or .matplotlib in your home directory aren't writeable by the user running your python script. (I'm doing a bit of guesswork here...)
What is it that you're trying to do?
cheers,
Chris

got this run time error from "from pylab import *".

Sorry, cutils.py is a part of a new config package we have been working on,
which ships with matplotlib but is not activated. I think you need to edit
your matplotlib/__init__.py instead, just make the same changes.
Once that change is made, and you try to import pylab, you should get a
RunTimeError telling you that matplotlib can't create the directory, either
because the path doesnt exist, or it exists but you cant write to it. At that
point you can set your MPLCONFIGDIR environment variable to point somewhere
writeable, and if it seems like a bug that matplotlib is trying to create a
directory somewhere nonsensical, please let us know.
