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)

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
[sudo] password for zishan:

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.
