What is SSH?

hello, i am making my MagicMirror by following this tutorial

https://forum.magicmirror.builders/topic/236/complete-setup-tutorial

after getting to the end and entering the:

pi@magicpi:~ $ cd MagicMirror/config
pi@magicpi:~/MagicMirror/config $ cp config.js.sample config.js

pi@magicpi:~/MagicMirror/config $ cd $HOME/MagicMirror
pi@magicpi:~/MagicMirror $ npm start

i receive a list of errors

npm ERR! Linux 4.4.50-v7+
npm ERR! argv “/usr/bin/nodejs” " /usr/bin/npm" “start”
npm ERR! node v6.10.2
npm ERR! npm v3.10.10
npm ERR! code ELIFECYCLE
npm ERR! magicmirror@2.1.1 startL ‘sh run-start.sh’
npm ERR! exit status 1

npm ERR! failed at the magicmirror@2.1.1 start script ‘sh run-start.sh’
npm ERR! make sure you have the latest version of node.js and npm installed.
npm ERR! if you do, this is most likely a problem with the magicmirror package,
npm ERR! not eith npm itself
npm ERR! tell the author that this fails on your system:
npm ERR! sh run-start.sh
npm ERR! you can get information on how to open an issue for this project with:
npm ERR! npm bugs magicmirror
npm ERR! or of that isnt available you can get their info via:
npm ERR! npm owner ls magicmirror
npm ERR! there is likely additional logging output above

npm ERR! please include the following file with any support requests
npm ERR! /home/pi/magicmirror/npm-debug.log

any ideas/help is appreciated,

thnx
