trouble importing xlwings module into python 2.7 on Mac

Question

I am attempting to use xlwings with Python 2.7.8 on Mac, but when I enter this code:

from xlwings import Workbook, Range, Chart

I receive this error message:

cannot import name Workbook

This appears to be the the same issue reported here with Python 3, but I am experiencing the same issue now with Python 2.7.8. I had no trouble importing mysql.connector so I don't think this is an issue with the Path variable.

Any help is greatly appreciated.

Thanks,

Ash
