Graphviz looks for non-existent file 'gvcache'

[Jonathan Turkanis]

I am running Trac 0.11 with Python 2.4. When I install and enable GraphvizPlugin 0.7.5 I get the following (santized) error:

OSError: [Errno 13] Permission denied: '/var/trac/projects/xxx/gvcache

You need to create a cache directory (that exists) then configure the plugin to use that cache directory. The default cache directory is gvcache.

Checkout the configuration section of ​http://trac-hacks.org/browser/graphvizplugin/0.11/README.txt

HTH,

And this will be handled by #3951.

Maybe this needs to be better documented on the project wiki page since it seems to be a fairly frequently asked question.
