Not using the Expo fork of react-native - react-native

Question

I'm using expo with react native. All is fine, but i get this warning and the app takes a long time in loading :
[exp] Warning: Not using the Expo fork of react-native. See https://docs.expo.io/.
How can i fix it please.

Answer 1

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.

Answer 2

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.
