vue-native-core: Setup with Vue Native Cli does not work

I am following the steps provided here -> https://vue-native.io/docs/installation.html The commands I am running:

1. npm install -g vue-native-cli
2. vue-native init myproject // Initializes crna project
3. cd myproject
4. npm install
5. npm start: 5a. starts metro bundler with text:

INFO 23:49 Starting Metro Bundler on port 19001. INFO 23:49 Metro Bundler ready.

1. I scan the Qr code with my iphone camera. 6.a expo app opens and the red screen with error on is there and my metro bundler writes:

ERROR 23:52 Unable to resolve “…/…/App” from “node_modules/expo/AppEntry.js” ERROR 23:52 Building JavaScript bundle: error
