Node.js找不到基本功能

Question

I just installed node.js(v7.1.0) and npm(3.10.9)with homebrew and I am trying to run a basic web server.

Edit* I now instantiate the dispatcher but still get the same error

---

var http = require('http');
var port = 8080;
var HttpDispatcher = require('httpdispatcher');
var http           = require('http');
var dispatcher     = new HttpDispatcher();

dispatcher.setStaticDirname(__dirname);
dispatcher.setStatic('');

dispatcher.onGet("/page1", function (req, res) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Page One');
});

var server = http.createServer().listen(port);


server.on('request', function (req, res) {
    console.log('GOT');
    dispatcher.dispatch(req, res);  
});

---

when I run the command node server.js I get this error

dispatcher.setStaticDirname(__dirname);

TypeError: dispatcher.setStaticDirname is not a function

I get the same error for the dispatcher.onGet call.

You are not using httpdispatcher correctly. You must instantiate the dispatcher before using it.

var HttpDispatcher = require('httpdispatcher');
var dispatcher     = new HttpDispatcher();
