我剛用安裝成功的nvm安裝了nodejs版本0.10.14.

在安裝nodejs之前,我安裝了zeromq 2.2.0版.

出于測試目的,我試圖在下面運行一個基本的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...");

但這是投擲錯誤 –

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 Object. (/home/zishan/newsURLCollector/testServer2.js:16:8)

at Function.Module._load (module.js:312:12)

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

at startup (node.js:119:16)

端口8800已經使用ufw打開了.

我試著谷歌搜索套接字繁忙的錯誤,但沒有運氣,我認為重新啟動Ubuntu是好的,問題變得更糟.當我重新登錄并嘗試再次運行上述示例時,系統會拋出消息：

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

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

* node

* nodejs-legacy

Try: sudo apt-get install

為什么地球上的工作節點停止工作并且無法找到節點.然后我按照系統提示,并在下面做了sudo apt-get install節點的結果：

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

[sudo] password for zishan:

The following package was automatically installed and is no longer required:

Use 'apt-get autoremove' to remove it.

The following NEW packages will be installed

zishan@news01:~$node -v

然后我試圖找到節點版本,但沒有發生任何事情,我現在沒有得到節點提示,但當我做“哪個節點”它說 – /usr/sbin / node

重啟后我不知道出了什么問題.任何人都可以解釋一下.
