无法安装Cordova android平台

6个月前，我启动了一个Ionic项目，但我一直无法在我的android设备上测试，因为我会出错。今天，我买了一台新电脑，从github上下载了我的文件，希望通过一台新电脑，我的android问题会得到解决，但事实并非如此

运行$ionic cordova run android--设备会导致：

cordova平台添加android--保存

---

你知道我应该做什么吗？我将感谢任何帮助

我也遇到过类似的问题。尝试删除节点\模块文件夹并再次添加。如果不起作用，请转到“C:\Users\Simon/.cordova/lib/npm cache/cordova android”目录，找到cordova提供的android版本，然后尝试cordova平台添加android@x.x.x用那个版本。如果有效，请告诉我。@sudarshanapreep我的主目录中似乎没有

.cordova

文件夹。你确定吗？它是一个隐藏的文件夹。
