Mac上安装node.js

var http = require('http');

http.createServer(function(request,response){
response.writeHead(200,{'Content-Type':'text/plain'});
response.end('hello world\n');
}).listen(8888);

console.log('Server running at ' target='_blank'>http://127.0.0.1:8888/');[/code] 
cd到正确路径下



打开浏览器，出现输入地址和端口号



yeah you succeed！
