Failed building JavaScript bundle. upgrade to 21


I am new to react and installed pomodoro from expo/pomodoroexp

It works well.

I am trying to update to sdk 21.
I updated package.json
@expo/vector-icons”: “~4.0.0”,
“expo”: “^21.0.0”,
“react”: “16.0.0-alpha.12”,
“react-native”: “”,
“react-native-drawer-layout”: “^1.3.2”

“sdk”: “21.0.0”,

import Expo, { Constants, Permissions, Notifications } from ‘expo’;

deleted directories .expo and node_modules
ran npm install

rebooted both machines

exp start -c

seems it built ok

when I attach from the phone I get:

Failed building JavaScript bundle

there is another image from the phone which means nothing to me

I would appreciate some help.
