Ionic v2 run on Android problem

Ionic Framework ionic-v3
1

When I’m using ionic run android there is no output and it’s nothing happens.

I have tried to make ionic build android and I got this error:

Error happened [TypeError: Path must be a string. Received undefined]

Any idea how to fix it?

And there is more some weird problems, I don’t know why but I have to make sudo ionic serve and not just ionic serve… It’s only in Ionic v2.

Thanks…
