COMPAT: Break in openpyxl (original) (raw)

• 3.4 build is now using current version of openpyxl (2.0.2), fix for this, see here: https://travis-ci.org/pydata/pandas/jobs/25510797
• change ci/requirements-2.7.txt to use last version (1.8.6); will need same import fixes

When I try to use DataFrame to_excel, I was given the following error. I am using Pandas 0.13.1, openpyxl 2.0.2

from openpyxl.style import Style
ImportError: No module named style
