[ckan-dev] ImportError: cannot import name get_library_registry

[Reinoud Bosch]

Thanks a lot for responding!

I've decided to try an install on a clean Ubuntu 13.04 system using package install for CKAN.

First I run Software Updater. Then I open a terminal; here are my installation notes (who knows these might be useful for anyone having trouble installing CKAN on Ubuntu 13.04):

sudo su 
→ password
apt-get install -y nginx apache2 libapache2-mod-wsgi libpq5
wget http://packaging.ckan.org/python-ckan-2.0_amd64.deb
dpkg -i python-ckan-2.0_amd64.deb
apt-get install -y postgresql solr-jetty openjdk-6-jdk
cd /etc/default
gedit jetty
	NO_START=0
	JETTY_HOST=127.0.0.1
	JETTY_PORT=8983
→ save and close
service jetty start 
→ solr works on localhost:8983/solr
mv /etc/solr/conf/schema.xml   /etc/solr/conf/schema.xml.bak
ln -s /usr/lib/ckan/default/src/ckan/ckan/config/solr/schema-2.0.xml   /etc/solr/conf/schema.xml
service jetty restart 
→ solr works again
sudo postgres psql -l 
→ utf ok
sudo -u postgres createuser -S -D -R -P ckan_default
→ ckanpassword
sudo -u postgres createdb -O ckan_default ckan_default -E utf-8
mkdir -p /etc/ckan/default
chown `whoami` /etc/ckan
apt-get install python-pastescript
easy_install -U Pylons
cd /usr/lib/ckan/default/src/ckan
paster make-config ckan /etc/ckan/default/development.ini
cd /etc/ckan/default
gedit development.ini
	sqlalchemy.url = postgresql://ckan_default:ckanpassword/ckan_default
	solr_url = http://127.0.0.1:8983/solr
→ save and close

So far so good; now the trouble starts. I follow suggestions from http://docs.ckan.org/en/ckan-2.0/install-from-source.html#postgres-setup

Here I go:

cd /usr/lib/ckan/default/src/ckan
paster db init -c /etc/ckan/default/development.ini

With repeated trying I get a number of messages indicating that modules are missing, so I install them:

easy_install fanstatic
easy_install sqlalchemy
easy_install repose.who
easy_install pyutilib.component.core
easy_install babel
easy_install genshi
easy_install vdm

Trying paster db init -c /etc/ckan/default/development.ini after that last easy_install gives me the message:

ValueError: VDM only works with SQLAlchemy versions 0.4 through 0.7, not: 0.8.2

This is when I currently give up. 

I tried the install from source but that proved even more tricky.

I have the feeling there should be an easier way to install required python-packages that could resolve this problem.

Do you have any idea?

Thanks so much,

Reinoud

new to project myself, but wondering if you have fantastic installed.
have you run
pip install -r requirements.txt
?

if so, make sure if you installed in virtual environment that you
activate that environment using the <virtenv>/Scripts/activate
