Cannot run android emulator

[wolfgangmeyers]

After running the install script and trying to launch an android device, I'm getting this output:

$ tns run android --emulator --justlaunch
Copying template files...
  ◠ Installing tns-androidInstalling  tns-android
/Users/wolfgang/code/foundateui
└── tns-android@3.0.0


The plugin tns-android@3.0.0 is already installed
TypeError: Path must be a string. Received undefined

Followed by usage information, and no emulator launches. Any idea what might be wrong here?

Mac OS 10.12.4, I believe everything else is the latest version. I can get more info if it helps.

maybe a node problem?

Can you check if you have dependency to tns-android in your package.json. If you have it - you can safely delete it.

You can also try to clear your node_modules and platforms folders and do a clean build.

I removed tns-android from my package.json, removed node_modules, removed platforms and re-ran tns run android. Works after that. Thanks!
