[ckan-dev] [ckan-discuss] Problem installing CKAN on debian lenny

Thu Mar 24 16:12:33 UTC 2011

Hi Rufus,

Thanks for your e-mail, but it's resolved. During the pip install of the
missing, present and conflict txt files I got an error (tested on debian
and ubuntu) that git is not installed (clean install). Since git is not
listed as a required package I din't see the error and got an error later
on in the installation.  

I got the error during this command:
pip install -r lucid_missing.txt -r lucid_conflict.txt -r
lucid_present.txt -e hg+http://bitbucket.org/okfn/ckan#egg=ckan
