javascript - node.js can't check version after installation on windows 10 -

i installed node.js version 4.4.1 on windows 10 , tried code tutorial internet. first thing recommended write "$ node -v", after i'm getting following error:

you're in node repl, not in windows' cmd (see node icon in title bar?). can directly write js in that.

to version, run node -v on windows' cmd.
