当我尝试运行以下命令时：
ionic platform add android
它返回以下错误：
Updated the hooks directory to have execute permissions
Running command: /home/vagrant/projects/financeApp/hooks/before_platform_add/init_directories.js /home/vagrant/projects/financeApp
Error: Failed to fetch platform android
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

我试图删除.cordova文件夹，我已经安装了Android SDK，控制台中的android命令工作，我添加了一个Android设备，但是无论何时我都使用cordova或者离子工作尝试添加一个平台。我在任何平台上都会遇到同样的错误。
