Description

Relevant issue/comment (cc @Titozzz ) : #19827 (comment)

As I am trying to upgrade from React Native 0.55.0 to 0.57.5, I am running into issues. Specifically, in Android (no problems in iOS), I am running into this issue:

react 16.6.1, react-native 0.57.5

yarn why metro
yarn why v1.10.1
[1/4] 🤔  Why do we have the module "metro"...?
[2/4] 🚚  Initialising dependency graph...
[3/4] 🔍  Finding dependency...
[4/4] 🚡  Calculating file sizes...
=> Found "metro@0.48.3"
info Reasons this module exists
   - "react-native" depends on it
   - Hoisted from "react-native#metro"
   - Hoisted from "react-native#metro#metro-config#metro"

Any ideas how to resolve the problem?

React Native 0.57 is not actively maintained anymore. Can you try upgrading to 0.59? It should be fixed there.

I've already updated, and I don't see this issue anymore.
