Success! Created AwesomeProject at /Users/sopheak/Documents/cam/react/AwesomeProject Inside that directory, you can run several commands:

npm start Starts the development server so you can open your app in the Expo app on your phone.

npm run ios (Mac only, requires Xcode) Starts the development server and loads your app in an iOS simulator.

npm run android (Requires Android build tools) Starts the development server and loads your app on a connected Android device or emulator.

npm test Starts the test runner.

npm run eject Removes this tool and copies build dependencies, configuration files and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

cd AwesomeProject npm start

Hey @hengsoheak, I was able to solve this issue. It had to do with the version of watchman I was running.

The steps I took:

1. npm uninstall watchman -g
2. brew install watchman
3. npm start from project directory

I had watchman installed globally with npm (wrong version maybe?). I uninstalled it and re-installed via brew and now it’s working again. I hope this helps.

I got this error, but then it went away when I bumped from jest version “jest”: “20.0.4” to “jest”: “23.2.0”
