react-native init project warnings and errors

Question

I always use to develop my projects natively for Android and iOS, but after many people talking to me about react-native, I decided to give it a try.

However, I got very frustrated at the very first initial step: create my first project.

This is my environment:

• macOS Mojave 10.14
• Xcode 10.0
• node v10.12.0
• watchman 4.9.0
• react-native-cli: 2.0.1

When I run the command react-native init AwesomeProject, I see many warnings like this:

This will walk you through creating a new React Native project in /Volumes/HD2/fabiobergmann/WebstormProjects/AwesomeProject

To run your app on iOS:
   cd /Volumes/HD2/fabiobergmann/WebstormProjects/AwesomeProject
   react-native run-ios
   - or -
   Open ios/AwesomeProject.xcodeproj in Xcode
   Hit the Run button
To run your app on Android:
   cd /Volumes/HD2/fabiobergmann/WebstormProjects/AwesomeProject
   Have an Android emulator running (quickest way to get started), or a device connected
   react-native run-android

Then, even with all these warning, I tried to run react-native run-ios, and I get these errors:

Any idea what is happening or a way to workaround it?

Answer 1

I was able to build and run my project following the instructions here.

More specifically:

# Clean cache
rm -rf $TMPDIR/react-*; rm -rf $TMPDIR/haste-*; rm -rf $TMPDIR/metro-*; watchman watch-del-all

# Open a new tab and Start Metro Bundler directly from the project folder
react-native start  --reset-cache

# Now run `react-native run-android` or `react-native run-ios`

It works, but starting like that, this makes me afraid to build a project using react native.
