ionic安装问题 ionic emulate android 出错

在安装ionic 后创建Android运行虚拟器出错
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_S_construct null not valid

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
