Angular.js tutorial running e2e test uisng protractor

I am following the Angular tutorial http://ift.tt/1lmmEA8 When I get to the last bit on the first page - "e2e using protractor", I do "npm run protractor" in a new command window with the local site running and karma running, but I get the below error log:
