Scikit-Learn Not Properly Updating in IPython

I am attempting to update scikit-learn within IPython to version 0.14 from 0.13 using the following command in the IPython shell:

!pip install scikit-learn --update

Everything appears to be updating, but when I look at the pip log I see the below (I would appreciate any insight):
