React-Native – undefined is not an object ("evaluating this._component.getScrollableNode")

I’m snuggling using react native, I’m not able to run my application.

I updated my react-native version from “^0.46.4” to 0.47.1 because ^0.46.4 I had a different error and react from ^15.6.1 to 16.0.0-alpha.12,
the previous error was

undefined is not an object (evaluating
‘_reactNative.PropTypes.string’)

that refers to this the update after react 15.5
https://facebook.github.io/react/blog/2017/04/07/react-v15.5.0.html

so I updated it using

npm install -g react-native-git-upgrade

and then

react-native-git-upgrade

according to this https://facebook.github.io/react-native/docs/upgrading.html

“react”: “^16.0.0-alpha.12”,
“react-native”: “^0.47.1”,

And I’m still having this error..
I’ll appreciate any help
