CKAN安装错误：站点ckan_default和datapusher不存在

Question

I am trying to install CKAN onto Ubuntu 13.10. (64bit) following these instructions . Python 2.7.5+ is installed on the machine. The following errors stop me from installing the CKAN package:

$ sudo dpkg -i python-ckan_2.2_amd64.deb
Selecting previously unselected package python-ckan.
(Reading database ... 289528 files and directories currently installed.)
Unpacking python-ckan (from python-ckan_2.2_amd64.deb) ...

Answer 1

Finally, I installed CKAN from source as suggested by the documentation :

This is the quickest and easiest way to install CKAN, but it requires Ubuntu 12.04 64-bit.
