Trying to start look, but get error #23

Open wegorich opened 9 years ago

wegorich commented 9 years ago

That error I receive at express 4.0 doing:

require('look').start();
Error: listen EADDRINUSE
    at exports._errnoException (util.js:746:11)
    at Agent.Server._listen2 (net.js:1146:14)
    at listen (net.js:1172:10)
    at Agent.Server.listen (net.js:1257:5)
    at Object.start (_debugger_agent.js:20:9)
    at startup (node.js:86:9)
    at node.js:814:3

What can be wrong?

@wegorich EADDRINUSE just means that something is already running on the port. It could be another instance of the same app running elsewhere, or something else entirely. To figure out what is running on the port, use the command

netstat -tulpn | grep 3000

The above command assumes 3000 is the port you're trying to run your application on.
