        } 
        #user-list { 
            list-style-type: none; margin: 0; padding: 0; 
            padding: 5px 10px; 
        } 
        #user-list .current-user { font-weight: bold; } 
    </style> 
</head> 

<body> 
    <div id="main"> 
        <ul id="messages"> 
            <!--<li class="my-message">Hi server</li>--> 
            <!--<li>Hello client</li>--> 
        </ul> 
    </div> 

    <div id="side"> 
        <p class="header">Online</p> 
        <ul id="user-list"> 
            <!--<li class="current-user">Fani</li>--> 
        </ul> 
    </div> 

    <form action=""> 
      <textarea name="messageText" autocomplete="off"></textarea> 
    </form>       
</body> 
</html>

this is server.js 这是server.js

var express = require('express'), 
    app = express(), 
    port = 3000 
    ; 

/** 
 * Meng-konfigurasi express untuk meng-look-up file html 
 * dari directory bernama "public" 
 */ 
app.use(express.static(__dirname + '/public')); 

/** 
 * Pada saat browser me-request path "/" 
 * response dengan file bernama "index.html" 
 */ 
app.get('/', function(req, res){
    res.sendfile('index.html'); 
}); 

/* 
 * Meng-konfigurasi express untuk listen pada 
 * port yang telah di tentukan 
 */ 
app.listen(port, function(){ 
    console.log('listening on *:' + port); 
});

then i try to run server.js with this command. 然后我尝试使用此命令运行server.js。

node-dev server.js

but i get this error.. 但我得到这个错误。

[root@server NoChat]# node-dev server.js

The error is quite clear: 错误很明显：

Error: Cannot find module 'express'

You do not have the module express installed. 您没有安装express模块。 To install it, run npm install express in the command line (while in the same folder as the server.js file). 要安装它， npm install express在命令行中（与server.js文件位于同一文件夹中）运行npm install express 。
