[ckan-dev] mod_wsgi error and mako templates

Mon Feb 11 11:34:52 UTC 2019

Hi List

I've just upgraded to the latest 2.7.5 patch release (it's never as easy as the docs make out!) and I'm getting a 500 error in the apache2 logs:

mod_wsgi (pid=5269): Target WSGI script '/etc/ckan/default/apache.wsgi' cannot be loaded as Python module.
mod_wsgi (pid=5269): Exception occurred processing WSGI script '/etc/ckan/default/apache.wsgi'.

TemplateEngineMissing: Please install a plugin for "mako" to use its functionality

I'm running CKAN 2.7.5 on Ubuntu 14.04 with Apache2 and Nginx.

Permissions on apache.wsgi are

-rw-r--r-- 1 www-data root  405 Dec 12 12:25 apache.wsgi

Contents of apache.wsgi are

import os
activate_this = os.path.join('/usr/lib/ckan/default/bin/activate_this.py')
execfile(activate_this, dict(__file__=activate_this))

from paste.deploy import loadapp

config_filepath = os.path.join(os.path.dirname(os.path.abspath(__file__)), 'production.ini')
from paste.script.util.logging_config import fileConfig
fileConfig(config_filepath)
application = loadapp('config:%s' % config_filepath)

Any pointers gratefully received
