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

端口8800已经使用ufw打开了.

我试着谷歌搜索套接字繁忙的错误,但没有运气,我认为重新启动Ubuntu是好的,问题变得更糟.当我重新登录并尝试再次运行上述示例时,系统会抛出消息：

zishan@news01:~/newsURLCollector$node testServer2.js

The program 'node' can be found in the following packages:

* node

* nodejs-legacy

Try: sudo apt-get install

为什么地球上的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,并在下面做了sudo apt-get install节点的结果：

zishan@news01:~$sudo apt-get install node

然后我试图找到节点版本,但没有发生任何事情,我现在没有得到节点提示,但当我做“哪个节点”它说 – /usr/sbin / node

重启后我不知道出了什么问题.任何人都可以解释一下.
