"Could not determine react-native-codegen location" after upgrading to 0.65

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

After an upgrade from 0.64.x to 0.65 I get:

Error: Could not determine react-native-codegen location. Try running 'yarn install' or 'npm install' in your project root.
Command PhaseScriptExecution failed with a nonzero exit code.

I confirm this is the case after a complete purge of node_modules, yarn.lock, Pods, Podfile.lock, Xcode build folder, and a fresh install/build too.

React Native version:

I’ve found out installing react-native-codegen as a dev dependency fixes the issue:

yarn add --dev react-native-codegen

But again, I think it should be subdependency of React Native and be installed by that instead of needing a manual install.

OMG. Ok it was react-native-codegen. I was using version 0.0.7 and when I upgraded to a newer one, it caused the error. I installed old version using ‘npm install react-native-codegen@0.0.7 -save-dev’ and that fixed the problem. Hopefully you don’t lose another 5 years on this issue!!
