No module named celery when installing ckanext-archiver

问题

I'm using CKAN as my open data portal and am trying to install the Archiver Extension by following the instructions at https://github.com/ckan/ckanext-archiver. However I am faced with this error which I could not solve after enabling the archiver in my ckan config file.

Traceback (most recent call last):

I have installed the extension from an activated virtualenv and the required libraries.

sudo pip install -e git+http://github.com/okfn/ckanext-archiver.git#egg=ckanext-archiver

Do not call sudo pip install when you are using virtualenv, just pip install.

I had some issues executing:

pip install -e git://github.com/okfn/ckanext-archiver.git#egg=ckanext-archiver

which resulted with

no matches found: git://github.com/okfn/ckanext-archiver.git#egg=ckanext-archiver

but below commands worked just fine:

cd /tmp/
git clone git://github.com/okfn/ckanext-archiver.git
pip install -e ./ckanext-archiver
pip install -r ckanext-archiver/pip-requirements.txt
