IPython console can't locate "backports.shutil_get_terminal_size" and won't load

I'm running Python2.7 on windows 10 doing env and most pkg management with Anaconda. After upgrading a number of packages, my ipython console now fails to start in any IDE or at the console. When I attempt to run it at the console I get this error:

Traceback (most recent call last):

File "C:Anaconda3libsite-packagesIPythonutilsterminal.py", line 27, in <module>
import backports.shutil_get_terminal_size
ImportError: No module named backports.shutil_get_terminal_size

The first thing I tried to do was:

pip install --upgrade backports.shutil_get_terminal_size

output:

Requirement already up-to-date: backports.shutil_get_terminal_size in c:anaconda3libsite-packages

I've uninstalled and reinstalled ipython with both

conda uninstall ipython
conda install ipython

and

pip uninstall ipython
pip install ipython

Still won't work. Help please!
