Duplicate Module Name: react-native

Question

I ran Pod Update in my XCode Project and now my project isn't compiling due to duplicate modules being downloaded. Anyone know any solutions?

Looking for JS files in    /Users/.../App/Finalv2    Metro Bundler ready.  Loading dependency graph...jest-haste-map: @providesModule naming collision:   Duplicate module name: react-native   Paths: /Users/.../App/Finalv2/node_modules/react-native/package.json collides with /Users/.../App/Finalv2/ios/Pods/React/package.json  This warning is caused by a @providesModule declaration with the same name across two different files. Loading dependency graph, done. 

UPDATE: I deleted my node_modules folder and package.lock.json and ran npm install but the issue is still there

EDIT:

Adding my Package.json

UPDATE

Running npm install gives a weird error

Answer 1

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 

Answer 2

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
