sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/local/lib/node_modules
...and...if you're on a mac (like I am), and still see errors after running these commands, then run this last one and you should be good. (Recommend you try testing before you do this one. I don't like changing the permissions on the ENTIRE /usr/local directory unless it really seems necessary!)

sudo chown -R $USER /usr/local

然后发现如下错误
npm ERR! tar.unpack untar error /var/folders/wh/2xdg6wvd5txbkprv3stwg6r40000gp/T/npm-40778-58f71719/registry.npmjs.org/cordova-app-hello-world/-/cordova-app-hello-world-3.9.0.tgz

 分开安装：


daweiMBP:~ dawei$ cordova -v
 
-bash: cordova: command not found
 
daweiMBP:~ dawei$ sudo npm install -g cordova

cordova 安装成功
tar.unpack untar error 即解压失败。这主要是由于npm文件夹操作是需要root权限的。
看了stackoverflow主要解决办法为：

   
   
   
   
   
sudo chown -R $USER ~/tmp
sudo chown -R $USER /usr/local/lib/node_modules
sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/local
sudo chown -R $USER /usr/bin/node
sudo chown -R $USER /usr/bin/npm
sudo npm cache clean


试尽各种办法，最后还是手动卸载了再重装了npm 1、sudo npm uninstall npm -g 如果步骤1卸不掉npm了（我就是这种情况） 2、进到npm的安装目录 /usr/local/lib/node_modules/npm/ sudo make uninstall 3、手动重装npm curl -L https://npmjs.com/install.sh | sh 然后，终于搞定了！抓狂啊！





	
		
		
	
	
		
     
     
     
     
     
 
      
 
       
 
        
Ionic 安装 helloword 演示以及 ionic 在 android 环境下面导航在最上面解决 方案 
 
        
1. 配置环境 
 
        
 
         
 
先安装 node.js 
 
 
         
 
安装 cordova 
 
 
        
 
       
 
      
 
      
 
       
 
        
 
         
npm install -g cordova sudo npm install -g cordova 注意:部分同学现在直接使用 npm install -g cordova 发现安装了以后 执行 cordova build 
 
         
android 的时候 提示需要安装 platform for android-21 sdk ,意思就是需要 最新版本的 sdk 
 
         
解决方法:
 1.更新 sdk (推荐) 翻墙 代理 或者想其他办法
 2.Sdk 没法更新的情况下面 可以先卸载当前的 cordova,然后再重新指定版本安装 cordova 3. 下载 sdk 包集成 推荐 http://bbs.phonegap100.com/thread-1566-1-1.html 
 
         
Android adt 离线包集成 sdk http://bbs.phonegap100.com/thread-1456-1-1.html
