Hello All,
I've been using zope and matplotlib for some time now, and I want to connect them. I'am using the example code from page: http://www.scipy.org/Cookbook/Matplotlib/Matplotlib_and_Zope , but whenever I try to import matplotlib, and/or pylab packages i get this error from zope:
Error Type: RuntimeError Error Value: '/' is not a writable dir; you must set environment variable HOME to be a writable dir
*wild guess* you are starting Zope as root (via init) so $HOME points to root's home directory (usually /root) Now zope switches to another user (configured or default to nouser and thus cannot write to root's home anymore. You can either set another value for $HOME in your zope.cfg - there is a section for custom environment vars or modify mathplotlib to _not_ write to $HOME. (Sounds like a bad idea anyway - whats wrong with temp?) Zope Products use ZOPEHOME and INSTANCE_HOME Regards Tino
