Invariant Violation: requireNativeComponent: "RNSScreen" was not found in the UIManager - react-native

Question

I am getting RNSScreen error even though I have installed all related packages and followed react-navigation guide (https://reactnavigation.org/docs/getting-started#installation) but nothing worked for me.

Answer 1

Faced the same issue while implementing Navigation. Run following commands
npm install #react-navigation/native
React Navigation is made up of some core utilities and those are then used by navigators to create the navigation structure in your app.
In your project directory, run:
npm install react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context #react-native-community/masked-view
This will install versions of these libraries that are compatible.
If you're on a Mac and developing for iOS, you need to install the pods to complete the linking.
npx pod-install ios
Now run
react-native run-ios

Answer 2

That usually happens when you install all packages to add navigation without terminating the running build. Make sure to stop the running process for ( android or IOS ) then run it again after installing them and adding the routing components

Answer 3

I think you are missing to install react-native-screens components. That is required part in install react navigation guideline.
Dont forget to run pod install in ios folder after install package from npm.

Answer 4

stop all the terminal servers and then run
npx react-native run-android
if it still does not work,
npm i react-native-screens
and then
npx react-native run-android

Answer 5

Close Metro and run npx run android to rebuild your code

Answer 6

This solution (source) always works for me, here is the exact solution:
If you're facing with this error
Invariant Violation: requireNativeComponent: "RNSScreen" was not found
in the UIManager.
Follow these steps:
1. Make sure in your `package.json` file if you have the following packages:
#react-native-community/masked-view#react-navigation/native#react-navigation/stackreact-native-gesture-handlerreact-native-reanimatedreact-native-safe-area-contextreact-native-screens
2. Next ensure if you have pods up-to-date (For iOS only) by making sure cd ios --> pod install --> cd ..
3. And finally cancel the current build by pressing Ctrl+C (twice/thrice) and then do npx react-native run-ios

Answer 7

RNSSCreens error because the react-native-screens isn't installed on the your project
just run npm install react-native-screens react-native-safe-area-context or if your using yarn run 'yarn add install react-native-screens react-native-safe-area-context'

Answer 8

As I don't have enough reputations to upVote the answer, I am mentioning the answer which worked out to me here
Solution mentioned by #Gurjinder Singh , worked smoothly..
Recapturing:
Issue : With Expo, Sanity.io app was working on device in dev, but once apk was generated using "eas build -p android --profile preview" , build was successful but when I tried opening the app in my mobile, after splash screen app was crashing.
Adblogcat showed : com.facebook.react.common.JavascriptException: Invariant Violation: requireNativeComponent: "RNSScreen" was not found in the UIManager.
Solution worked:
npm install #react-navigation/native
npm install react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context #react-native-community/masked-view
thanks to community and #Gurjinder Singh (top voted)

Answer 9

Hey i was also facing same problem . Just use
npm install react-native-screens
.

Answer 10

This was happening to me on both iOS and Android. I managed to get Android working again by updating the package:
"react-native-screens": "^3.18.1"
Then adding this to dependencies in: android/app/build.gradle
implementation project(':react-native-screens')
Then adding this to protected List getPackages() in: android/app/src/main/java/com/myapp/MainApplication.java
#Override
protected List<ReactPackage> getPackages() {
#SuppressWarnings("UnnecessaryLocalVariable")
List<ReactPackage> packages = new PackageList(this).getPackages();
packages.add(new com.swmansion.rnscreens.RNScreensPackage());
return packages;
}
NOTE: Make sure you don't already have an import for com.swmansion.rnscreens otherwise the app will keep rebooting due to duplicate screen views
Then finally adding this to android/settings.gradle
include ':react-native-screens'
project(':react-native-screens').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-screens/android')
Make sure you clean gradle before running the app, for example navigate to android folder and run:
./gradlew clean
As for iOS, just add this to target 'myapp' do in: ios/Podfile
pod 'RNScreens', :path => '../node_modules/react-native-screens'
Make sure you delete your Podfile.lock and then run pod install --repo-update in your iOS folder before running the app.

Answer 11

Happy Update: react-native-screens 3.18.2 is out with a fix for this, if you were impacted by the 3.18.1 release that caused compile problems (which you can check by seeing the message below, if needed)
So, mostly obsolete now answer preserved below, but just updating packages should get you moving. Cheers
Nowadays if this is happening it is because react-native-screens 3.18.1 includes new configuration that is only compatible with react-native 0.69+
If you are using an older react-native you need to make sure your react-native-screens dependency is exactly 3.18.0:
"react-native-screens": "3.18.0",
then likely a npx react-native start --reset-cache to restart your javascript bundler with a fresh cache.
You will know if this is your problem if you see something like this when you say npx react-native run-android:
warn Package react-native-screens has been ignored because it contains invalid configuration. Reason: "dependency.platforms.android.componentDescriptors" is not allowed
There may be a 3.18.2 soon with a fix - reference: https://github.com/software-mansion/react-native-screens/issues/1614#issuecomment-1276245207

Answer 12

I've encountered the same problem, and solved it.
You can just close the terminal and app on Android Emulator(or device), and just run npm run android or react-native run-android again.
I think they might have some cache and occur the error.
I hope you can fix the problem.

Answer 13

Close the Metro and IOS simulator.
Ensure you go to your ios folder run pod install
Reopen your simulator
This should solve the problem. I also use quite a while to figure it out

Answer 14

I worked on this problem for several days and this is want worked for me:
In the android\app\src\main\java(your project name)\MainApplication.java
add to Imports:
import com.swmansion.rnscreens.RNScreensPackage;
Then add new RNScreensPackage() to the ReactPackage List:
#Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
...
new RNScreensPackage()
);
}
Edit: This was after I tried everything else here.

Answer 15

This helped me. install this package
npm i react-native-screens
and add
import { enableScreens } from 'react-native-screens';
enableScreens();

Answer 16

You go into the ios folder of your project folder and run the following command.
pod install
Then run the simulator.

Answer 17

You must have react-native-screens installed and I'm guessing that you have done it. So, I will just you a Problem that maybe is not really clear in the documentation.
So you probably just Install React Navigation on your app.
Once you installed it, you need to restart you app.
So close your app, run react-native run-ios or react-native run-android again.
React navigation Install some native modules. Thus, you need to restart that app as I mention.
This is really clear on their documentation.

Answer 18

I also came across the same problem. For Android, I uninstall the app from the emulator then build the app again.Problem solved. Assuming that you already installed packages you need.

Answer 19

Just stop running your node server and build the app again from Xcode/Android Studio or using command react-native run-ios or react-native run-android

Answer 20

In case you are on android, you need to rebuild using npx run android or react-native run-android
The new installed apk will work fine

Answer 21

I also get this error and after doing these steps my app starting running
cd android
./gradlew clean (for windows or linux)
npm install react-native-screen
react-native start & react-native run-android

Answer 22

worked for me yarn add react-native-reanimated
"#react-navigation/native": "^6.0.10", "#react-navigation/native-stack": "^6.6.2", "react": "17.0.2", "react-native": "0.68.2", "react-native-reanimated": "^2.8.0", "react-native-safe-area-context": "^4.3.1", "react-native-screens": "^3.13.1", "styled-components": "^5.3.5"

Answer 23

you must clear the Metro bundler cache
run the following command :
expo start -c

Answer 24

Finally found the solutions, first by creating new project and secondly re-setup of the react-google-maps library.
Workaround Solution: Created new project, installed all dependencies from scratch, followed step-by-step installation guidelines of react-native screens, and finally moved all my code files into a newly created project. This worked for me :D
After digging into the project code and compared project code with newly generated code, here are my findings:
Actual Problem: We had integrated react-native-google-maps library some time ago, for which I and other developers followed step-by-step guidelines and made changes in the MainActivity.java file in the android folder. There were some misconfigurations due to which RNSScreen issue was getting thrown.
Actual Solution Removed react-native-google-maps completely (uninstalled npm packages) and removed Google Maps configuration and did set up the react-google-maps library again
In conclusion, if any of the developers, try to set up google maps in react native, please check the version of react native and react-native-google-maps library and then follow the steps carefully.
Hopefully, this would answer your queries.

Answer 25

In my case, the following code block helped!
npm install react-native-screens
npm run android/ ios

Answer 26

(It Workes For Me..!)
for React-native developers..
Some times the changes of packages Not reflacted in xcode so follow this steps for Solution..
Open Project in xcode ->
Clean Buid Folder ->
(Rebuid Your Project)Run on any Simulator and wait for Build..
->Once Build either You can run again by Terminal or continue work by xcode..

Answer 27

none of the recommended answers worked until I tried what I found in this comment plus restart my steps:
deleting the node_modules directory
turn Metro and actually quit the simulator completely
yarn to install again
start metro via npx react-native start
install pods via npx pod-install ios
run simulator again via npx react-native run-ios

Answer 28

Make sure the below plugin install and linked with android & ios?
npm install react-native-screens
If not linked then perform the below command
react-native link react-native-screens
after successfully linked for android and ios, "Sync Gradle" from android studio and "pod install" for ios
Now close the terminal and again build and run app

Answer 29

I updated Expo to 45.0.0. That fixed the error and solved a problem with the app crashing after launch in production mode but working fine on device with QR code or simulator.

Answer 30

You need to do a few things:
Open android/app/src/main/java/MainApplication.
Replace the function getPackages() with:
#Override protected
List<ReactPackage> getPackages() {
#SuppressWarnings("UnnecessaryLocalVariable")List<ReactPackage> packages = new PackageList(this).getPackages();
// Packages that cannot be autolinked yet can be added manually here, for example:
// packages.add(new ReactNativeFirebaseAuthPackage());
return packages;
}
yarn start --reset-cache or npm start -- --reset-cache
Clean:
cd android
./gradlew clean
