Environment
Environment:
OS: macOS High Sierra 10.13.3
Node: 8.9.1
Yarn: Not Found
npm: 5.5.1
Watchman: Not Found
Xcode: Xcode 9.2 Build version 9C40b
Android Studio: 3.0 AI-171.4443003
Packages: (wanted => installed)
react: 16.2.0 => 16.2.0
react-native: 0.53.0 => 0.53.0
Steps to Reproduce
- Initiate a new React Native project using
react-native init projectName - Run the command
react-native run-ios --device deviceName
Expected Behavior
The app should have launched on my physical device. Additionally, if I already have an instance of Metro Bundler running using react-native start, it should just hook into that one and use that.
Actual Behavior
Metro Bundler opens and complains that Metro Bundler can't listen on port undefined. It then prompts the user to hit enter because the process has terminated. I've run into other random errors too. I've included one of those here as well.
Metro Bundler error 1
Metro Bundler error 2
Additionally, there is a lot of output in my main terminal about the Xcode build failing. I can include the full output in a comment below if requested.
Even if I try running an instance of Metro Bundler using react-native start before running react-native run-ios --device deviceName, it just starts a new instance in a new terminal window.
Reproducible Demo
You can reproduce this with a brand new project created using react-native init projectName.
