I was trying to install ionic and create a sample project on it since morning. But, was facing a series of issues since then. Tried solving them one by one. Atlast restarted my machine and opened command prompt to build the sample project and tried

path of the sample project> ionic build android

但是，我一直面临错误，指出离子"未被识别为内部或外部命令.

But, i kept on facing the error that states 'ionic' is not recognized as an internal or external command.

我尝试清除缓存并在我的机器中重新安装 ionic.尽管如此，我仍然面临同样的问题，即 ionic 未被识别为内部或外部命令.

I tried clearing the cache and reinstalling ionic in my machine. Still, I face the same issue of ionic is not recognized as an internal or external command.

有人可以帮我解决这个问题吗?
