I have searched the web for a solution to the following problem and nothing
works.
I call matplotlib code from a python script (2.5) running on Apache2.2 and
mod_python. When I get to the point where I the code is to save a figure in
the website dir I get the following error.
File "/usr/lib/python2.5/site-packages/matplotlib/__init__.py", line 324, in
_get_configdir
raise RuntimeError("'%s' is not a writable dir; you must set environment
variable HOME to be a writable dir "%h)
RuntimeError: '/root' is not a writable dir; you must set environment
variable HOME to be a writable dir
The code that creates the fig is a follows:
import matplotlib
from matplotlib import pylab as plt
import numpy as np
matplotlib.use('AGG') # use a nongui backend
matplotlib.rdParams['MPLCONFIGDIR']='/var/www/modtest/'
...
plot code here
...
plt.savefig('/var/www/modtest/plot_data/' + plotfile[0]) # use 1st
generated random file name
First can anyone tell me what "HOME" variable the error message is referring
to?
I have changed the $HOME env variable under linux Ubuntu Gutsy
I have added a $HOME variable to httpd.conf, however I am not an
experienced Apache user
I can get the code to work from the interactive.py shell
