"Error: Native module not found" error when using uuidv4 in React Native app (non Expo)

Describe the bug

When I try to use uuidv4 in my vanilla react native (non-Expo) app, I’m getting “Error: Native module not found” error. I’m importing the two needed dependencies correctly as far as I can tell, and the same way worked for my Expo app:

import 'react-native-get-random-values';
import {v4 as uuidv4} from 'uuid';
...
// some where in my render() function
const myID = uuidv4(); // throws error

I’ve verified /node_modules has the two packages downloaded correctly too.

How to reproduce

Basically what I described above - I’m using basically a blank RN app.

Expected behavior

uuidv4() should work with react-native-get-random-values imported above it.

[…] make react-native-get-random-values a peerDependency of your library and document the necessary steps to install it.

This is what I would recommend as well 👍

I think we can close this one now since a workaround have been found, there doesn’t seem to be anything we can change in uuid, and there hasn’t been any recent activity…

I think the fact that a manual npx pod-install is currently necessary in order to install react-native-get-random-values is something that cannot be fixed in uuid but would have to be approached in https://github.com/LinusU/react-native-get-random-values, so feel free to raise an issue over there.

Until then I think the best bet is to make react-native-get-random-values a peerDependency of your library and document the necessary steps to install it.

Maybe one more idea: Have you tried adding react-native-get-random-values as a dependency to your library and the necessary manual install steps in a postinstall hook?
