EAS build fails from nx-monorepo due to missing dependencies, yet hook that should fix package.json runs without issues about eas-cli

Hey, I think you are right, the build agent output for the Read package.json step should respect that the pre-install hook changed the file 👍

Issue open on nx: nrwl/nx#22195

It appears that the .npmrc file is required for the installation on EAS to run correctly. Once I copied the .npmrc file to the nx-expo-test root folder the build works.

This seems to be an issue with the nx-generator so maybe this issue can be closed, but it seems that the build agent output for the Read package.json step should respect that the pre-install hook changed the file which it currently does not seem to do.

.npmrc

strict-peer-dependencies=false
auto-install-peers=true
node-linker=hoisted

apps/nx-expo-test/package.json

Add && cp .npmrc apps/nx-expo-test to the end of the eas-build-pre-install script so that it is also copied along with the lock file.
