cordova build android 报错 ANDROID_HOME is not set

Question

运行

$cordova build android

[Error: ANDROID_HOME is not set and "android" command not in your PATH. You must fulfill at least one of these conditions.]
ERROR building one of the platforms: Error: /Users/albert/Bloom/BloomateStore/platforms/android/cordova/build: Command failed with exit code 2
You may not have the required environment or OS to build this project

请问这个ANDROID_HOME应该如何设置，在网上找了一圈，都没有解决这个问题
PS:
OSX系统 build ios 成功了
android 之前 build 成功过 现在则一直报这个错，不知道是动了哪里了

Answer 1

ANDROID_HOME是环境变量，指向你的Android SDK目录如果是windows的话直接设置即可。
*nix/OSX 使用.bashrc export一下。

Answer 2

在环境变量里面配置，变量名为ANDROID_HOME，变量值为你安装android-sdk的地址,你也可以参考http://www.ifcoder.us/看看
