我在我的ionic项目中运行了以下命令

ionic cordova platform add android

我得到了错误

> cordova.cmd platform add android
Using cordova-fetch for cordova-android@^9.0.0
Failed to fetch platform cordova-android@^9.0.0
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

我尝试了移除和添加cordova等解决方案，以及stackoverflow中给出的其他解决方案，但都不起作用。
谁能帮我解决这个问题？谢谢）
