Question

我正在关注nodejs-drawing-game，一个socket.io（http://tutorialzine.com/2012/08/nodejs-drawing-game/）的示例程序，使用railwayjs框架创建一个新副本（ http://railwayjs.com/）。顺便说一句，我的开发环境是Win7的node.js版本。

我可以在我的本地电脑上运行nodejs-drawing-game本身但是当我把它作为wailwayjs的模块运行时，我没有幸运。我是node.js，railwayjs的新手...任何人都可以帮助我克服这个问题？任何帮助表示赞赏。

        title: "draw#index"
    });
});

var draw_app = {
    init: function(){
        // Including libraries
        var io = require('socket.io').listen(app);

        // Delete this row if you want to see debug messages
        io.set('log level', 3);

        // Listen for incoming connections from clients
        io.sockets.on('connection', function (socket) {

            // Start listening for mouse move events
            socket.on('mousemove', function (data) {

                // This line sends the event (broadcasts it)
                // to everyone except the originating client.
                socket.broadcast.emit('moving', data);
            });
        });
