problem encountered running 'npm start' in "Programming WebRTC" book
Hello Karl @karlstolley,
In the section called “Finding Your Way Around the Code Directory” you write:
“…you can simply run npm start on your command line to fire up the server”.
But doing so I get:
ksrtc@0.2.0 start
PUBLIC=www DEBUG=signaling-server: node ./scripts/start-server
‘PUBLIC’ is not recognized as an internal or external command,
operable program or batch file.
Can you please help me with this.

Sure, Yehuda. Those are just shell variables, so let’s start with some really basic things:
- What operating system are you running?
- What version of node are you running (
node -vwill tell you) - What version of npm are you running (
npm -vfor that) - What exact command did you run?
npm run startis what you need to run –ksrtc@0.2.0is not itself executable.
Let me know if you have any success, or further trouble. We’ll get this sorted out!
