Joblib dependency + Error messages

[ragbadaskar]

This is the error I get on after pip install roro and after roro ps

(background-img) MacBook-Air-3% roro ps Traceback (most recent call last): File "/Users/ragbadaskar/pythoncode/pydev/background-img/bin/roro", line 7, in <module> from roro.cli import cli File "/Users/ragbadaskar/pythoncode/pydev/background-img/lib/python3.5/site-packages/roro/__init__.py", line 4, in <module> from .projects import get_current_project File "/Users/ragbadaskar/pythoncode/pydev/background-img/lib/python3.5/site-packages/roro/projects.py", line 5, in <module> from . import models, config File "/Users/ragbadaskar/pythoncode/pydev/background-img/lib/python3.5/site-packages/roro/models.py", line 3, in <module> import joblib ImportError: No module named 'joblib'

Can we have better error messages?
