in node.js 7.4.0 :

node app.js /node/realtime-multiplayer-in-html5/node_modules/socket.io/lib/store.js:35 Store.prototype.proto = EventEmitter.prototype; ^

TypeError: Cannot read property 'prototype' of undefined at Object. (/node/realtime-multiplayer-in-html5/node_modules/socket.io/lib/store.js:35:41) at Module._compile (module.js:571:32) at Object.Module._extensions..js (module.js:580:10) at Module.load (module.js:488:32) at tryModuleLoad (module.js:447:12) at Function.Module._load (module.js:439:3) at Module.require (module.js:498:17) at require (internal/module.js:20:19) at Object. (/node/realtime-multiplayer-in-html5/node_modules/socket.io/lib/manager.js:16:13) at Module._compile (module.js:571:32)

but it's working in 6.9.3 node.js
