I downloaded Twilio and I know it's sitting in the right path, but when I tried this 

```
import twilio

```

This is the error message that popped up

```
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/twilio/__init__.py", line 3, in <module>
    from six import u
ImportError: No module named six

```

I don't know what this means or what I did wrong. I'm doing the Udacity course on learning python so that is why I need twilio. Any help would be awesome!
