Export error using omekacsv.py

I'm trying to export items from my class's Omeka site using omekacsv.py from https://github.com/wcaleb/omekadd#omekacsvpy . I'm encountering the following error:

Traceback (most recent call last):
File "./omekacsv.py", line 3, in <module>
from omekaclient import OmekaClient
File "/Users/carrie/GitHubRepos/omekadd/omekaclient.py", line 1, in <module>
import httplib2
ImportError: No module named httplib2

I've tried to check out the code, and I'm not sure what is wrong. (Not a Python or an Omeka expert.) Can anyone give me some tips on how to make this script work?

I've checked the forums but don't see this particular question.

Many thanks.

That looks like a python module, httplib2, not being installed on your system. That'll be the first thing to check.

An issue on that GitHub repo might help, too, since he knows python better than I do.

Thanks so much. I searched online for the module, installed it, and it works like a charm.
