How to conveniently install cx_Freeze for Python 3?
Download the cx-freeze-python3_4.3-0ubuntu0px0pre2_amd64.deb from Launchpad.net.
Install that .deb file with the command:
sudo dpkg -i [.deb file name]
Run this exactly (or copy it into the terminal):-
sudo pip3 install cx_freeze
You mispelled the module's name. It is cx_freeze, not cx-freeze. BTW, I am having problems with this for some reason, although it used to work before. Anyways, this is going to work for you cause I am using a ported version of Ubuntu (Ubuntu MATE for RPi 2, for the interested).
