I created all the files from the lesson and wrote node server.js in the console.

It turns out that:

 events.js:154 throw er; // Unhandled 'error' event ^ Error: listen EADDRINUSE :::8080 at Object.exports._errnoException (util.js:856:11) at exports._exceptionWithHostPort (util.js:879:20) at Server._listen2 (net.js:1236:14) at listen (net.js:1272:10) at Server.listen (net.js:1368:5) at Server.listen.Server.attach (/Users/doge/node_modules/socket.io/lib/index.js:216:9) at new Server (/Users/doge/node_modules/socket.io/lib/index.js:50:17) at Function.Server (/Users/doge/node_modules/socket.io/lib/index.js:38:41) at Object.<anonymous> (/Users/doge/Desktop/server.js:2:31) at Module._compile (module.js:413:34)

Tell me how to make it work?

There is an explicit error: EADDRINUSE
(" E rror: ADDR ess IN USE ", "Error: the address is already taken").

In order to start, you can change the port ( 8080 ) to another: for example, 8081 .

This is a mistake of the fact that you have already started node.js on this port or the port is busy. If node.js already running on this port, just kill the process with sudo fuser -vk 8080/tcp . If the port is busy, for example, it can be running apache , then run node.js on another port, for example, on 8888 .
