javascript - Node.js 找不到基本功能

Question

我刚刚用自制软件安装了 node.js(v7.1.0) 和 npm(3.10.9)，我正在尝试运行一个基本的 Web 服务器。

编辑* 我现在实例化调度程序但仍然得到相同的错误

---

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);  
});

当我运行命令 node server.js 时出现此错误

dispatcher.setStaticDirname(__dirname);

TypeError: dispatcher.setStaticDirname is not a function

我在 dispatcher.onGet 调用中遇到了同样的错误。

您没有正确使用 httpdispatcher。您必须在使用前实例化调度程序。

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