Duplicate Module Name: react-native

I just spent some time searching around for a solution and finally found something that worked! I'm not using Firebase, but the discussion here was able to help: https://github.com/invertase/react-native-firebase/issues/414 You have to add two lines to your Podfile.

# Add these to your Podfile
pod 'React', :path => '../node_modules/react-native'
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

Then run the following to make sure you reinstall your CocoaPods.

cd ios
rm -rf Pods
pod install

Try:

1. watchman watch-del-all
2. rm -fr $TMPDIR/react-*
3. erase jest-cache folder
4. rm -rf node_modules
5. npm install
6. npm cache clean && npm start -- --reset-cache

Update

Also try to download the latest node js and run npm install -g npm

remove the "React" folder inside of your "Pod" folder

add this inside of your pod file at the bottom after the last end

post_install do |installer|
  installer.pods_project.targets.each do |target|

# The following is needed to ensure the "archive" step works in XCode.
# It removes React & Yoga from the Pods project, as it is already included in the main project.
# Without this, you'd see errors when you archive like:
# "Multiple commands produce ... libReact.a"
# "Multiple commands produce ... libyoga.a"

    targets_to_ignore = %w(React yoga)

    if targets_to_ignore.include? target.name
      target.remove_from_project
    end

  end
end

remove your Pods folder and then go pod install
