One proper way to install pip and wireless in a dual Python environment (i.e. stock OS X Python 2.7 and brew's Python 3.6.1) is the get-pip.py method outlined here: How do I use pip 3 with Python 3.4?.

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py
sudo ln -s /usr/local/bin/pip2.7 /usr/local/bin/pip2 #usually not necessary because pip2 already exists
sudo python3 get-pip.py


Then depending where you want to install wireless either

sudo pip2 install wireless #installs to /Library/Python/2.7/site-packages/wireless


or

sudo pip3 install wireless #installs to /usr/local/lib/python3.6/site-packages/wireless


or both.
