I use django-wkhtmltopdf to generate PDF documents. I described a clear path to the django-wkhtmltopdf.
WKHTMLTOPDF_CMD = '/home/vagrant/envs/vagrant/lib/python2.7/site-packages/wkhtmltopdf'
I get the error:
[Errno 13] Permission denied
Permissions in the path to the django-wkhtmltopdf:
drwxrwxr-x 3 vagrant vagrant Feb 17, 4096 7:32 wkhtmltopdf
What worked for me was:
In settings.py specify the FULL path to the binary file like:
WKHTMLTOPDF_CMD = '/home/stefanos/vEnvs/assembla/lib/python2.7/site-packages/wkhtmltopdf/wkhtmltopdf'
You need to install wkhtmltopdf itself, and specify the path to the binary (either in /usr/bin or /usr/local/bin).
