I just updated cordova via sudo npm install -g cordova
Now i have the problem, that everytime when i try to build the android app with 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 is working fine so i think it's a problem with android?
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)
The combo i have:
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
回答1:
The file 'platforms.json' in the platforms folder is missing. Run the commands to remove platforms and add platforms.
$ cordova platform rm android
$ cordova platform add android
Confirm this works for you.

$ ionic state reset
$ ionic info
My system information:
Cordova CLI: 5.4.1
Gulp version: CLI version 3.9.0
Gulp local: Local version 3.9.0
Ionic CLI Version: 1.7.11
Ionic App Lib Version: 0.6.5
ios-deploy version: 1.8.3
ios-sim version: 5.0.4

Node Version: v4.2.3
Xcode version: Xcode 7.2 Build version 7C68

Depending on the version you are using:
sudo npm install cordova@5.4.0 -g
I originally installed the latest but since it won't build my stuff, I installed 5, which incidentally, installs 5.4.1 and I was getting the same error.
Downgraded to 5.4.0 and it works just fine.
