这个组件的安装问题

[Harris-Aaron]

你好， gou yu 先生，我在使用你的 wifi-io https://github.com/wifi-io/sdk/ 组件时遇到了问题，它是不能成功安装的

npm install wifi
npm ERR! Darwin 15.4.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "wifi"
npm ERR! node v5.3.0
npm ERR! npm v3.9.3
npm ERR! code ENOSELF

npm ERR! Refusing to install wifi as a dependency of itself

我将你的项目文件克隆到/wifiDemo/node_modules/wifi

node wifi.js

module.js:328
throw err;
^

Error: Cannot find module 'sdk'

她提示我无法找到该模块

下面是我的wifi.js (也就是 app.js)

var express = require('express');
var app = express();

var Wifi = require('wifi');

app.get('/', function(req, res) {
res.send('Hello WIFI!');
});

// 初始化
var wifi = new Wifi({
username: 'xxx',
password: 'xxx'
});

// 获取token, Token 会被保存在 wifi.token 备用
wifi.token(function(err, result) {
console.log(result.body);
});

app.listen(8012);
