Description
Minimal reproducible example
https://github.com/johnneast/expo-turbo-repo
Which package manager are you using? (Yarn is recommended)
yarn
If the issue is web-related, please select the bundler (web.bundler in the app.json)
metro
Summary
When creating a brand new expo app in a monorepo (in this case created by turborepo), the metro bundler for the app does not work, so running yarn web in the app folder results in the following error:
λ .expo/static/render.js ░░░░░░░░░░░░░░░░ 0.0% (0/1)Error: ENOENT: no such file or directory, open '/Users/johneast/src/scratch/my-turborepo/node_modules/@expo/server/src/index.ts'

Metro error: Unable to resolve module ./node_modules/expo-router/entry from /Users/johneast/src/scratch/my-turborepo/apps/app1/.:
None of these files exist:

Reproducing
The above can be reproduced by simply creating a new monorepo and then creating a new expo app.
yarn create turbo
cd my-turborepo
yarn create expo
# app created at apps/app1
cd apps/app1
yarn webThe above errors will be out to the console.
The app works fine in Expo Go.
Creating an expo app in the monorepo that does not use expo-router (index.js in the route of the project etc) works as expected.
building the app and deploying the dist folder works as expected.
