I have installed react-navigation in my React Native project. Its a starter project doesn't have any codes. But while running project I am facing error like this.

Here is my Navigation code

import { createStackNavigator } from 'react-navigation';

import Home from './screens/Home';
import WeatherDetail from './screens/WeatherDetail';


const Navigation = createStackNavigator({
  Home: { screen: Home },
  WeatherDetail: {
  screen: WeatherDetail
 } 
});

export default Navigation;

And here is the App.js codes

 import Navigator from './Router';


 export default class App extends Component {
   render() {
     return (
       <View style={styles.container}>
         <Navigator />
       </View>
     );
    }
  }

If I remove the navigator component from the App.js and replace it with a Text the application runs without any error.

  1. remove node_modules and package-lock.json
  2. npm install
  3. npm install --save react-navigation
  4. npm install --save react-native-gesture-handler
  5. react-native link

Debug and check each element in that filtered array you are trying to map to see if all of the nested objects exist for each of the elements. undefined is not an object (evaluating &#39;object.keys(routeConfigs )&#39;) &quot;react-navigation&quot;: &quot;^4.0.10&quot;, &quot;react-navigation-drawer&quot

If you are using react-link to link your dependencies:

  1. 0pen your ios Podfile and delete all yout linked dependencies: pod 'xxxxxxx', :path => '../node_modules/xxxxx
  2. Close Xcode
  3. In your /ios folder run "pod update"
  4. In your project source run "react-native link"
  5. Open Xcode and Clean Build Folder from Xcode Menu -> Product
  6. Run your application from Xcode
  7. Link manually the dependency "react-native-gesture-handler" into your Xcode Project following steps in documentation: https://facebook.github.io/react-native/docs/linking-libraries-ios
  8. Now run your application from Xcode, you should be fine.

If you are calling the function with quicksort(). you are not passing any arguments in. However, your function starts with function  TypeError: undefined is not an object (evaluating 'screen.orientation.angle') #144. DispatchCommit opened this issue May 19, 2020 · 1 comment Labels. bug good first

First, remove node_modules and package-lock.json and run npm install. After installing the react-navigation package in your React Native project. You should install react-native-gesture-handler. If you’re using Expo you don’t need to do anything here, it’s included in the SDK. Otherwise:

npm install react-native-gesture-handler

And finally, link gesture dependency as:

react-native link react-native-gesture-handler

This answer based on the React Navigation document.

Unhandled JS Exception: TypeError: undefined is not an object (evaluating 'this.​_subscribableSubscriptions.forEach') #17348. Closed. Attempting to use TabBarIOS results in TabBarIOS.Item being undefined. Can&#39;t build any project using TabBarIOS - tested on 0.59.4 through 0.59.8. React Native version: 0.59.8 info React Native

From the official doc:

If you're on React Native >= 0.60, you need to disable autolinking for react-native-gesture-handler first. To disable autolinking for it, create a react-native.config.js file in the root of your project with the following content:

module.exports = {
  dependencies: {
    'react-native-gesture-handler': {
      platforms: {
        android: null,
        ios: null,
      },
    },
  },
};

If your are using React 0.60, just omit this official doc. Follow following steps:

  1. rm react-native.config.js if exist
  2. react-native link react-native-gesture-handler
  3. cd ios && pod install && cd ..
  4. react-native run-ios

I get the same error on ios from RN v0.60

The following worked for me:

cd ios
pod install

  • This all looks correct, can you show the code for the Home component?
  • You need to link it with react-native link I guess.
  • I was facing the same problem in iOS. In that case you can try to add RNGesture library manually. tuntunir.blogspot.com/2019/02/…
  • If the error persists even after all the steps, it is because of backslashes, then change this line of code to this: project(':react-native-gesture-handler').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-gesture-handler/android')
  • following these steps as well as uninstalling the app then rebuilding worked for me.
  • Is it also true in expo project? Because it is not written anywhere.
  • Excellent. Simplest (and probably most correct) solution. This answer should be moved up!
  • I don't think you need step 1 and 2 for this, but always good to be thorough.
  • Please keep in mind, that linked content might be moved or deleted, then your answer might get useless. Better is to mention the link but include the most useful content of this linked content into your answer.
