CKAN Development Install Issue: AttributeError: &#

Question

I've done a CKAN development install and am running with debug = true in my development.ini file. On visiting localhost:5000 I get an error with a traceback whose end point is the error:

AttributeError: 'module' object has no attribute 'css/main.debug.css'

Caused by the call in lib/helpers.py:

r = getattr(fanstatic_resources, resource)

Any idea what I'm doing wrong and what I can do to fix this error.

Answer 1

I'm using an ubuntu 12.04 and experiencing some problems with this

Was getting this error after following Sean's answers and running

npm install less nodewatch

and got this error:

Found another thread that explains this and offers the solution to execute

npm config set registry http://registry.npmjs.org/

However after running the above command I am getting this error:

Seems like the version are incompatible or could this be the problem with node and node.js?

Answer 2

I got few errors while installing the packages. Following is the solution (according to official CKAN docs) for impatient:

cp /usr/lib/ckan/default/src/ckan/ckan/public/base/css/main.css /usr/lib/ckan/default/src/ckan/ckan/public/base/css/main.debug.css

Answer 3

Beware that apt-get install nodejs installs nodejs and NOT node in /usr/bin, at least in Ubuntu 12.10 (I didn't check in other distributions). This throws errors since both ckan/bin/less as well as ckan/node_modules/less/bin/lessc are calling node. So either create a softlink in /usr/bin or modify the scripts (#!/usr/bin/env nodejs).

Answer 4

You need to run the less script from the bin directory in the CKAN source code to build the main.debug.css file. There is some documentation of this but it's not yet integrated with the rest of the CKAN docs (i.e. there's no link to it anywhere, we have a ticket to fix this).

This works on Ubuntu 12.04, you might need to have your virtualenv active when you do this:

sudo apt-get install nodejs npm
npm install less nodewatch
./bin/less # Assuming you're in your ckan dir e.g. `~/pyenv/src/ckan`

Now restart the paster serve development.ini command and it should work.

Generally speaking whenever running CKAN 2.0 for development you should:

• Have debug = True in your ini file
• Have ./bin/less running in a terminal all the time
