There have been some issues getting everything properly installed for the Scribbler Bot project on OS X. It worked for me the first time because I used Homebrew and pip instead of the .mpkg installers. I've done this three times now and it has worked every time, so this should work for you too.
All code blocks are meant to be pasted into the Terminal.
