      OS: Windows 10

      Memory: 8.52 GB / 15.95 GB
    Binaries:

I'm upgrading from React Native 0.56.0.

Description

Continuing on from #20710 since 1 disruptive comment there is too heated, and apparently it's better to lock that issue instead of just deleting said comment and not bar anyone including myself from adding to my own bug report there. (please ease on the heavy handed moderation, locking everything isn't the way unless you want 0 feedback from everyone)

Now I'm hitting this:

Metro still?

Reproducible Demo

I first ran yarn add react-native@0.57.0-rc.0 without issue, and modified my .babelrc to

{
  "presets": ["module:metro-react-native-babel-preset"],
  "plugins": ["idx"]
}

Then I ran react-native upgrade, and I get output above under Description.
