# Fresh SDK upgrade fails at pod install with a Mapbox clash, while a sibling app on the same SDK builds

> A fresh install pulled newer patch versions of Expo packages than the known-good app's lockfile, and the newer Expo modules clashed with Mapbox's prebuilt binaries.

iOS. Likely fix, 9 October 2026.

Versions: Expo SDK 57, @rnmapbox/maps

There is no error message for this one, only the symptom in the title.

## Cause

A fresh install pulled newer patch versions of Expo packages than the known-good app's lockfile, and the newer Expo modules clashed with Mapbox's prebuilt binaries.

## Fix

Pin the shared packages to the exact versions from the known-good lockfile, remove packages the app does not need, then run `npx pod-install` locally before spending a cloud build.
