执行cordova build android命令报错信息如下：

报错了，ANDROID_HOME没有配置，需要说明的是，如果先安装了Android Studio等Android的开发环境，这些变量是应该已经配置好的，因为本机没有装Android Studio所以没有配置，那在环境变量里补上。

我把Android的SDK放在了D:\Android\sdk目录下，在环境变量里添加：

ANDROID_HOME=D:\Android\sdk

还要添加java的环境变量：

JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_55

然后在PATH里添加：

%ANDROID_HOME%;%JAVA_HOME%\bin;

%ANDROID_HOME%\build-tools;
%ANDROID_HOME%\platform-tools;
%ANDROID_HOME%\tools;

然后 一定要关闭当前的nodejs窗口再重新打开 ，不然新配置的不会起作用。
