If you create a react native app with the command from the getting started page: $create-react-native-app AwesomeProject then the package.json file has the following dependencies:
"dependencies": {
"expo": "^20.0.0",
"react": "16.0.0-alpha.12",
"react-native": "^0.47.0"
}
If you create an app directly in the Expo XDE, you will see in the package.json, they use a fork of react-native:
"dependencies": {
"expo": "^20.0.0",
"react": "16.0.0-alpha.12",
"react-native": "https://github.com/expo/react-native/archive/sdk-20.0.0.tar.gz"
},
Changing the react-native module path to https://github.com/expo/react-native/archive/sdk-20.0.0.tar.gz and running npm install will fix the problem.

That's how I fixed it:
- I updated my "react-native" dependency to the latest one available:
"https://github.com/expo/react-native/archive/sdk-23.0.0.tar.gz"
- I removed all dependency that I had installed by mistake in my previous expo app that actually required react-native link using the npm uninstall --save command:
react-native-image-to-base64, react-native-cloudinary
- Then I also had to remove them from the General > Linked Frameworks and Libraries
Now it works! I'm having issues with the Facebook Login now but at least it doesn't crash my app.
Good luck to you.
package.json. There's not enough information in your question as-is to help you.
