npx react-native run-macos does not start metro #2208

Open coolsoftwaretyler opened 1 week ago

coolsoftwaretyler commented 1 week ago

Environment

react-native -v: 14.0.0
npm ls react-native-macos:react-native-macos@0.75.6
node -v: 22.8.0
npm -v: 10.8.2
yarn --version: 1.22.22
xcodebuild -version: Xcode 15.4, Build version 15F31d

Steps to reproduce the bug

Follow the React Native macOS setup from the docs (for the most part, the current docs are actually a little out of date, but this will be the steps for an up-to-date RN project)

  1. npx @react-native-community/cli init macapp
  2. cd macapp
  3. npx react-native-macos-init
  4. npx react-native run-macos

Expected Behavior

I expected the app to build and run the starter project.

Actual Behavior

The app will build, but it doesn't automatically start Metro:

Not a big deal, I can just run:

yarn start

Then tap "reload"

Everything works great from there. I also did not have this issue when following the instructions for RN 0.71:

npx react-native@latest init <projectName> --version 0.71.0

Additional context

Happy to submit a PR if this is a quick fix and y'all know how to fix it but don't have the time to code it up.
