我刚用安装成功的nvm安装了nodejs版本0.10.14.在安装nodejs之前,我安装了zeromq 2.2.0版.

出于测试目的,我试图在下面运行一个基本的pub示例.

var zmq = require('zmq');
var socket = zmq.socket('pub');

console.log("Binding socket on port 8800...");

socket.bind('tcp://localhost:8800', function(err){
    if(err){
        console.log(err)
    } else{
        console.log("listening on port 8800");
    }
});
socket.send("hello this is testServer2 on port 8800...");

但这是投掷错误 -

events.js:72
    throw er; // Unhandled 'error' event
          ^
TypeError: Socket is busy
    at Socket._ioevents (/home/zishan/node_modules/zmq/lib/index.js:198:22)
    at Socket._flush (/home/zishan/node_modules/zmq/lib/index.js:343:23)
    at Socket.send (/home/zishan/node_modules/zmq/lib/index.js:318:42)

    at Function.Module.runMain (module.js:497:10)

端口8800已经使用ufw打开了. …
