pip and pip3 - both pointing to python3.5?

pip3 looks like the default option pip uses. Try using pip2 instead to explicitly install a Python 2 package.

Just change the first line of the /usr/local/bin/pip to:

#!/usr/bin/python

and the first line of /usr/local/bin/pip3 to:

#!/usr/bin/python3

And then it will act normally:

> pip -V
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)
> pip3 -V
pip 9.0.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)

python -m pip

This will use the version of pip that python can see.
