During this activity, i had uninstalled cordova on my machine but was not able to install it again.
error:npm wont install packages "npm ERR! network tunneling socket could not be established, cause=Pause Error" (http://i.stack.imgur.com/L6Hm5.png )
Jan suggested me to try http://stackoverflow.com/questions/32783561/npm-wont-install-packages-npm-err-network-tunneling-socket-could-not-be-esta… and then i tried with
npm config set proxy false
npm cache clean
i was able to install cordova (same version 5.4.1 as it was before) and then HAT installation worked successfully.
Thanks Jan for your support. #HappyLearning
