【nodejs】 npm 注意事项

1.安装时要切换到nodejs根目录，  否则就会安装到安装时所在的目录

2.要有管理员权限（win）

3.官方demo 提供比较全的依赖配置 http://www.hacksparrow.com/jquery-with-node-js.html

4.看一个demo

var $ = require(‘jquery‘);var http = require(‘http‘);

var options = {    host: ‘jquery.com‘,    port: 80,    path: ‘/‘};

var html = ‘‘;http.get(options, function(res) {    res.on(‘data‘, function(data) {        // collect the data chunks to the variable named "html"        html += data;    }).on(‘end‘, function() {        // the whole of webpage data has been collected. parsing time!        var title = $(html).find(‘title‘).text();        console.log(title);     });});
