Can you run react-native info and edit your issue to include these results under the Environment section?

If you believe this information is irrelevant to the reported issue, you may write `[skip envinfo]` alongside an explanation in your Environment: section.

Yes, I have the same issue, I've just init a new project and just hit react-native run-android and got the same error.

[samad324]

but my old projects are working fine!

[samad324]

my issue was resolved my downgrade react and react-native version to:
"react": "16.6.3",
"react-native": "0.58.4"

I have the same issue, it happens with both iOS and Android. It can be gotten around by killing the metro bundler then running react-native start. This happened after upgrade from .58 to .59.1
