Problems using Phonegap

I'm trying to use Phonegap for the first time, but I'm having problems.

I already had NodeJS installed, I was able to install Phonegap with npm install phonegap with no problems. Then, as suggests , I created an app with phonegap create myapp without problems, but when trying to run with phonegap run android I got the following error :

C:\Users\MEU_USUÁRIO\Desktop\myapp>phonegap run android
[phonegap] detecting Android SDK environment...
[phonegap] using the local environment
[phonegap] adding the Android platform...

Searching the web, there are several different solutions, apparently each solution works for a different case. I tried npm install cordova , set JAVA_HOME , ANDROID_HOME , Path , installed Ant and set ANT_HOME e nothing said served me, I continue with the same error.

The solution presented this other question did not serve me. I do not know what else to do.

Remember that AndroidSDK + Eclipse was already installed and worked before I even installed Phonegap. I'm using Windows 7.
