ionic build android 抛出“呃哦！”更新cordova后出错

我刚刚通过更新科尔多瓦sudo npm install -g cordova

现在我遇到了问题，每次我尝试使用以下命令构建 Android 应用程序时ionic run android --device i get

Error during processing of action! Attempting to revert...
ERROR running one or more of the platforms: TypeError: Uh oh!
Invalid Version: undefined
You may not have the required environment or OS to run this project

or ionic build android

Error during processing of action! Attempting to revert...
Error: Uh oh!
Invalid Version: undefined

IOS 运行正常，所以我认为这是 Android 的问题？

Android SDK Tools: 24.3.4
Android SDK Platform-tools: 23.0.1
Android SDK Build-tools: 23.0.2
SDK: Android 5.1.1 (API 22)

我有的组合：

Cordova CLI: 5.4.1
Ionic Version: 1.1.0
Ionic CLI Version: 1.7.10
Ionic App Lib Version: 0.6.5
ios-deploy version: 1.7.0 
ios-sim version: 4.1.1 
OS: Mac OS X El Capitan
Node Version: v0.12.7
Xcode version: Xcode 7.1 Build version 7B91b

平台文件夹中的文件“platforms.json”丢失。 运行命令以删除平台和添加平台。

$ cordova platform rm android
$ cordova platform add android

确认这对您有用。
