我刚刚使用 nvm 安装了 nodejs 版本 0.10.14，它安装成功。
同样在安装nodejs之前，我安装了zeromq版本2.2.0。
出于测试目的，我尝试运行下面的基本酒吧示例。
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...");
但它抛出了错误 -
events.js:72
throw er; // Unhandled 'error' event
^
TypeError: Socket is busy

端口 8800 已使用 ufw 打开。
我尝试用谷歌搜索套接字繁忙错误，但没有运气，比我想象的重新启动 Ubuntu 更好，问题变得更糟。当我重新登录并尝试再次运行上面的示例时，系统会抛出以下消息：
zishan@news01:~/newsURLCollector$ node testServer2.js
The program 'node' can be found in the following packages:
* node
* nodejs-legacy
Try: sudo apt-get install <selected package>
到底为什么工作节点停止工作并且无法找到节点。然后我按照系统提示做了sudo apt-get 安装节点下面是结果：
zishan@news01:~$ sudo apt-get install node
[sudo] password for zishan:

zishan@news01:~$ node -v
然后我尝试查找节点版本，但什么也没发生，我现在没有收到节点提示，但是当我执行“哪个节点”时，它说 - /usr/sbin/node
重启后不知道出了什么问题。任何人都可以解释一下吗？
