android - ionic build android 在更新 cordova 后抛出 "Uh oh!"错误

Question

我刚刚通过 sudo npm install -g cordova 更新了 cordova

现在我遇到了问题，每当我尝试使用 ionic run android --device 构建 android 应用程序时，我都会得到

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

或ionic build android

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

IOS 运行良好所以我认为这是 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

Answer 1

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

确认这对你有效。
